After cells take up one form of this molecule, it becomes accessible for antibody labeling after its target is hydrolyzed with HCl (“h-c-l”) and borax. That form of this molecule is often co-stained with Ki67 (“k-i-67”). This non-methylated molecule is the larger product (-5[1])of a reaction catalyzed by APOBECs, which underpins (-5[1])the first (-5[1])step of bisulfite sequencing. Ethynyl- and bromo·de·oxy (15[1])derivatives of this molecule are used to detect cell proliferation. (-5[1])The letter (*) psi (10[1]-5[1])denotes a form of this molecule that may help strengthen binding to the 30S subunit (-5[1])in one structure’s stem-loops. (-5[1])This molecule (-5[1])is generated by de·aminating (-5[1])cytosine, (10[1])and methylating (10[1])this (10[1])molecule’s (10[4]-5[1])5’ (“five-prime”) carbon yields its more mutation-resistant (-5[2])analog (-5[1])that (10[1])similarly forms two hydrogen bonds with adenine. (10[1]-5[1])For 10 (-5[1])points, (10[2]-5[2])what base (10[1])replaces (10[1]-5[1])thymine (10[5])in RNA? (10[4])■END■ (10[21]0[4])
