The existence of thymine in DNA instead of uracil is apparently due to evolution process which made DNA more stable. Thymine has greater resistance to photochemical mutation, making …

2017年4月4日 · Benefit of using thymine rather than uracil. For DNA the benefit is clear and stated in the question. By not using uracil as the complement to adenine, uracil produced by …

2013年3月5日 · Excess thymidine in a mitotic cell generates negative feedback on the production of deoxycytidine triphosphate from cytidine-5'-phosphate.

2014年12月13日 · RNA has three main characteristics that differs it from DNA. RNA is very unstable and decomposes rapidly. RNA contains Uracil in place of Thymine; RNA is almost …

2017年4月1日 · Conversion of uracil to thymine requires energy, meaning uracil is energetically less expensive than thymine. This also directly explains (partly) why mRNA doesn't …

2013年7月3日 · Wikipedia says that "in RNA, thymine is replaced with uracil in most cases." I'm curious what are the cases when this does not happen? Does this ever occur in normal …

2017年6月7日 · Poly(T) is an oligonucleotide with only repeating thymine residues. These are generally used as primers in Reverse Transcription PCR, as mature eukaryotic mRNAs have a …

2016年2月22日 · Note in Table 5.1 that all the adenine:thymine and guanine:cytosine ratios are close to 1, whereas the adenine-to-guanine ratio varies considerably. The meaning of these …

2017年3月3日 · UV-B radiation directly attacks DNA, it excites atoms of adjacent thymine molecules, which in turn form covalent bonds with each other and lead to formation of thymine …

2020年4月5日 · The GenBank entries for these are currently in DNA format. Thus V00642.1 contains references to the 1976 MS2 paper by Fiers et al. , but is in DNA format. As GenBank …
