$5$-Methylcytosine

Vedclass · Answer

(D) Spontaneous point mutations often occur due to the deamination of $5$-methylcytosine. When $5$-methylcytosine undergoes deamination,it is converted into thymine. Since thymine is a natural base in $DNA$,the repair mechanisms of the cell often fail to recognize this as a mutation,leading to a permanent $C \rightarrow T$ transition mutation. Therefore,$5$-methylcytosine is considered a 'hotspot' for spontaneous mutations.
