Capitalization

5-Methylcytosine is not normally capitalized in the middle of sentences in journal articles. I'm not familiar with the Wikipedia standard, but I've stuck to the capitalization that is used in the scientific literature; is it really a good idea to use a standard that deviates from this? - Madprime 20:46, 9 May 2006 (UTC)

From the ACS Style Guide, Chapter 7:

Chemical names are not captialized unless they are the first word of a sentence or are part of a title or heading. Then, the first portion of the syllabic portion is capitalized, not the locant, stereoisomer descriptor, or positional prefix.

That's the same style that should be used in Wikipedia too. Wikipedia:WikiProject Chemicals/Style guidelines. --Ed (Edgar181) 10:23, 12 May 2006 (UTC)

T4 Bacteriophage

Is it worth nothing that 5-methylcytosine exists in place of cytosine in T4 phage DNA? This is certainly the reason I was looking it up, but I'm insecure enough in my chemistry knowledge to not want to make the addition without consultation. The reading I have done indicates that this might protect the phage DNA from destruction by host processes. P4limpsest (talk) 15:57, 24 March 2008 (UTC)

Figure not correct?

Isn't the figure just cytosine? there is no methyl group ??

In the skeletal formula of 5-methylcytosine, the extra line relative to cytosine indicates the methyl group. -- Ed (Edgar181) 15:07, 8 December 2009 (UTC)

• 
  Cytosine
• 
  5-Methylcytosine

Wouldn't it be better to mention the role of that extra line? I too was unaware of that convention and thought the figure was incorrect. I'm going to add a brief sentence to the first section, see if it is accpetable. Thanks, HHHEB3 (talk) 14:41, 13 June 2010 (UTC)

Citation Needed

Will somebody please provide a citation for the following section

"The NH2 group can be removed (deamination) from 5-Methylcytosine to form thymine with use of reagents such as nitrous acid; cytosine deaminates to uracil under similar conditions."

Thank you

Need a citation for the lead section. I plan on extensively editing the page so I will add one - Davidjpod (talk) 23:08, 4 December 2019 (UTC)
