Question

Quizplus · Accepted Answer

All the listed mechanisms (deamination of a cytosine base into a uracil base, benzo(a)pyrene conversion of guanine to a thymine base, and deamination of 5-methyl cytosine into thymine) can lead to point mutations by altering the structure of a single nucleotide base, which can change the genetic code at a specific point.
