I think people who create and write, it actually does flow-just flows from into their head, into their hand, and they write it down.
A major type of UV light induced damage is the formation of cyclobutane pyrimidine dimers (PyrîîPyr) between adjacent pyrimidine bases in DNA exposed to UV radiation in the range of 200â300 nm (far-UV) [1] and [2] .
During protein biosynthesis, DNA is transcribed into RNA, another type of ribonucleid acid. In RNA, the DNA base thymine is replaced by uracil, a fifth nucleotide which is almost chemically identical to thymine, but lacks its 5â² methyl group. Cytosine can deaminate spontaneously to produce uracil (U).This process is referred to as hydrolytic deamination.uring protein biosynthesis, DNA is transcribed into RNA, another type of ribonucleid acid.
