Question

In a mutational event, when adenine is replaced
by guanine, it is a case of
(a) frame shift mutation
(b) transcription
(c) transition
(d) transversion

Answer 1

Answer:

In the case of transition, purine base is replaced by another purine (i.e., A-G) and pyrimidine is replaced by another pyrimidine (i.e., C-T) and vice versa. In the case of transversion, purine is replaced by a pyrimidine and vice-versa. The frameshift mutation is the mutation of bases in DNA sequence that changes the way of reading the sequences. Transcription is the process of formation of mRNA from DNA. Thus, the correct answer is option D
