Explanation:
Answer:
D. deamination of cytosine to uracil
Explanation:
Hydrolytic DNA damage is usually a consequence of metabolic reactions and the most common example of this type of damage is hydrolysis of cytosine into uracil with the release of ammonia. This damage can be fixed by the cell's DNA repair system:removal of uracil by an enzyme uracil-DNA glycosylase and consequently generation of an abasic (AP) site. AP endonucleases recognise AP site and break a phosphodiester bond so that lesion can be replaced with another cytosine.
