Here Colson and Sisson are lying, there can be no other word for it. The trial was not over the racism and eugenics promoted in the book. The trial was specifically and only over the teaching of evolution in the standard textbook, "Civic Biology" (which expended but two sentences on Darwin, and all of five or six pages on evolution, and even that treatment tepid and Lamarckian rather than Darwinian). The "Darwinists" did not insist that Scopes had a right to teach the racist and eugenic sections of the book; neither did the Creationists demand that they be removed. As point of fact, after Scopes was convicted, for the next edition of "Civic Biology," the author and publisher calmly erased all positive references to evolution and Darwin, while leaving unexpurgated all the racism and eugenics - and the State of Tennessee continued to buy the book and feed it to school kids for many years after. Creationists showed no objections or outrage, nor did they advance censorious legislation. The Creationists cared little about eugenics, and positively advocated racism; what they objected to was evolution.
For however much Creationists thrive on bitter fantasies about their own history, Tennessee schools had been segregated and had taught racism long before Civic Biology went to paper, and remained so long after it ceased to advocate evolution. Indeed, most public and private institutions in Tennessee were segregated and remained legally segregated until in the 1960s, when forced to stop by the Federal government. And so it was and has been the case in every state, evolution-free, dominated politically and socially by white Fundamentalist Protestants.
And Chuck Colson knows this: for thirty-five years ago, he and Harry Dent, a former aid to Strom Thurmond, were assigned by then-President Nixon to develop Nixon's racist "Southern strategy," intended to convert traditionally Democratic white Southerners to Republicans, using racial code words. Colson cannot claim ignorance of Southern political history.
Creationists' revisionist history of the Scopes Affair as a trial against racism is an invention of recent years, possibly only now that white Southern Fundamentalist Protestants have for the most part ceased publicly to advocate racism. It is a fraud, pious and perverse, existing only for Creationists' cynical campaign against science.
I need to make some minor corrections. In my first paragraph I write:
"As point of fact, after Scopes was convicted, for the next edition of 'Civic Biology,' the author and publisher calmly erased all positive references to evolution and Darwin, while leaving unexpurgated all the racism and eugenics - and the State of Tennessee continued to buy the book and feed it to school kids for many years after. Creationists showed no objections or outrage, nor did they advance censorious legislation. The Creationists cared little about eugenics, and positively advocated racism; what they objected to was evolution."
My "calmly erased" was inaccurate; there was evidently something of a tizzy between the author, George W. Hunter, and the publisher before a new, expurgated edition could be issued. Meanwhile, a year after the trial, the publisher issued a temporary special edition for sale to Southern states, with all six pages on evolution removed and unreplaced, and all else the same. A year or so later, they issued Hunter's revision, "A New Civic Biology," which is the one I was referring to in my post. The word "evolution" was banished entirely, as were the several illustrations that had upset Bryan so mightily at the trial. Brief and neutral mentions were made of "natural selection" and Darwin.
Most importantly, my comment "The Creationists [...] positively advocated racism" was meant as a general statement about Tennessee Creationists at that time and is untrue in respect to Bryan. Bryan never, to my knowledge, advocated racism. On the other hand, while he does not seem to have been personally racist, by the 'teens and 'twenties his primary constituency was Southern voters, in whose consideration he ignored the segregation and official racism of the entire region.

5-methylcytosine is the only significant modified nucleotide in the human genome. Up to 5% of all cytosine residues can be methylated in some tissues under some conditions. Typically, in an average human genome about 3% of the C's are methylated. Since cytosine makes up about 25% of the total nucleotides, this means that 0.75% of the total nucleotides contain methylated bases.
Flowering plants also have a high percentage of methylated cytosines in their genomes but most other eukaryotes have very little of this modified base. In addition to 5-methylcytosine, there are about a dozen other modified bases in DNA from various species. The most common ones are N6-methyladenosine, N2-methylguanosine, N4-methylcytidine, and 5-hydroxymethylcytidine. None of these are present in the human genome.
> (2) Is it recorded in the data from the human genome project?
No. The way DNA sequencing is done it isn't possible to distinguish between 5-methylcytosine and unmodified cytosine. However, we know that the methylated version is created by an enzyme that recognizes the dinucleotide -CG- and methylates the C. The vast majority of methylated C's are at -CG- dinucleotides. These dinucleotides can be located in the human genome sequence where they tend to occur in clusters called CG islands. We can predict regions of the genome that are likely to contain a high proportion of 5-methylcytosine by mapping the location of the CG islands. These CG islands tend to be located near the promoters of genes, which is consistent with the idea that methylation of C plays a role in the regulation of gene expression in mammals.
> (3) Is this base replicated faithfully? (How faithfully?)
During DNA replication 5-methylcytosine is recognized as C and a G is inserted in the opposite strand. 5-methylcytosine base pairs with G and when the G is copied during DNA replication a normal C is inserted in the opposite strand. This normal C can then be modified to 5-methylcytosine once DNA replication is complete.
If you start with 5-methylcytosine in the two C's of a double-stranded -CG- sequence, you will end up with daughter DNA strands that have a 5-methylcytosine in one strand and a normal C in the other strand.
m m -CG- ----> -CG- + -CG- -GC- -GC- -GC- m m
This is because DNA replication is semi-conservative. Each new daughter molecule contains one parental strand and one newly replicated strand.
Now, here's the neat part. Notice that the two new daughter strands are "hemimethylated." In other words only one strand contains a methylated C residue. The methylation enzyme specifically recognizes the hemimethylated DNA and not DNA where neither C is methylated. Thus, the methylation enzyme will scan newly replicated DNA looking for -CG- sites where one the the strands has a 5-methycytosine and the other strand does not. When it finds these sites it methylates the normal C on the opposite strand.
In this way the original methylated site is preserved after DNA has been replicated. This is the basis of many epigenetic effects where specific base modification is preserved from one generation to the next. If a gene is regulated in one cell by methylating -CG- islands, then this will be preserved when the cell divides. If, on the other hand, the gene has been regulated by removing the 5-methylcytosine (by a demethylase enzyme) then this pattern will also be preserved when the cell divides because neither of the daughter strands will have a 5-methylcytosine.
> (4) What happens if this base appears in a region of coding DNA?
5-methylcytosine does not seem to affect RNA polymerase so the DNA is copied as though it had C instead of 5-methylcytosine. The messenger RNA (mRNA) is normal and protein synthesis is normal. The presence of 5-methylcytosine in DNA mostly affects the binding of regulatory proteins to DNA itself. This can have an effect on whether a nearby gene is transcribed or not transcribed and that's why 5-methylcytosine is often found at -CG- rich sequences near transcription start sites (promoters). (The role of methylation in regulating transcription is controversial. It's also possible that methylation affects transcription indirectly by altering the packaging of DNA into chromatin.)
The presence of 5-methylcytosine in coding regions is probably irrelevant. It's an accidental by-product of the methylation reactions.

I will propose the following dilemma, and call it the Davey dilemma:
Science is the process of learning definite things about the world by taking data as reliable [lemma 1]
Anything that is logically possible is not in contradiction to science, even if it claims that all data are created as they hit our retinas. [lemma 2]
So, the Davey dilemma is that science is at the same time founded on reliable data that are unreliable.

This is a non sequitur. I am not talking about you personally. I am talking about the fact that you make religion deny what science is, and attempt to insert a religious view in its place. Science is the single most successful epistemology ever invented. It actually works. It does not involve revelations, intuitions, mystical visions or the operations of deities. This is to say it is emphatically not a religion. So, when you say:
> You don't have to reject science entirely at all. You can accept science
> in full, but just not make a religion out of it.
and yet you equally say that you will ignore scientific results when they contradict your interpretation of religion, you contradict yourself at the base. Either you think science is a way of knowing, in which case when science tells you the earth is 4.5by old you should accept that until science (good science!) tells you otherwise, or you reject the idea that science is a way of knowing. You cannot pick and choose truth here. If science tells you what is true, even allowing that it is a fallible way to find this out, then you are not at liberty to say "Oh, yes, all that is true except for the bits I think contradict my sacred texts". As soon as you do that, you adopt an epistemic nihilism about science. Since we know pretty well all we know through science, you have in effect declared the world to be unknowable.
Equivocate how you like, soften the blow and give whatever ground you can, this is the logical implication of your views, and it means that in the end the entirety of knowledge in your opinion comes down to people trading doctrinal blows. I think this is purely false. The world is known by the employment of empirical science, and any other claims to knowledge, such as through revelation, etc., have to not contradict science. As I said elsewhere once, if religion contradicts science, so much the worse for religion. The religion either has to realise it made a mistake, or abandon all claims to the ability to know anything, replacing all knowledge with pure faith.
The orthodox catholic (both lowercased to indicate the broad traditions rather than the denominations) Christian tradition has been that faith and reason cannot conflict as two truths cannot be in conflict. The way you set it up, if faith and reason conflict, you will hold fast to the prejudices of your faith ("prejudice" means, literally, "judging before"). In short, you abandon one truth on the basis that you judged before the facts were in, and you were correct from the start. Even the various churches do not take such a nihilistic stance.
