Vedclass · Answer

(A) In genetics,point mutations are classified based on the chemical nature of the base change:$1$. Transition: $A$ purine ($A$ or $G$) is replaced by another purine,or a pyrimidine ($C$ or $T$) is replaced by another pyrimidine.$2$. Transversion: $A$ purine is replaced by a pyrimidine,or a pyrimidine is replaced by a purine.Analysis of the given mutations:- $A$ to $G$: Purine to Purine $\rightarrow$ Transition- $C$ to $T$: Pyrimidine to Pyrimidine $\rightarrow$ Transition- $C$ to $G$: Pyrimidine to Purine $\rightarrow$ Transversion- $T$ to $A$: Pyrimidine to Purine $\rightarrow$ TransversionTherefore,the sequence is Transition,Transition,Transversion,and Transversion.
