Transition

Vedclass · Answer

(A) In genetics,a point mutation is a change in a single nucleotide base pair. Transitions are a specific type of point mutation where a purine is replaced by another purine (e.g.,$A \leftrightarrow G$) or a pyrimidine is replaced by another pyrimidine (e.g.,$C \leftrightarrow T$). Transversions,on the other hand,involve the substitution of a purine for a pyrimidine or vice versa. Therefore,the correct term for the substitution of a purine with another purine or a pyrimidine with another pyrimidine is Transition.
