Vedclass · Answer

(C) Point mutation is a change in a single base pair of $DNA$. Chemical mutagens can induce such mutations by acting as base analogs. $5$-Bromouracil is a base analog of thymine. During $DNA$ replication,it can be incorporated into the $DNA$ strand in place of thymine. Due to its tautomeric shifts,it can pair with guanine instead of adenine,leading to a transition mutation ($A-T$ to $G-C$ or vice versa).
