A) Deletion
B) Insertion
C) Frame shift
D) Point mutation
Correct Answer: B
Solution :
Insertion of a base adenine has occured in the original sequence \[\underset{\begin{smallmatrix} \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\text{ }\!\!'\!\!\text{ A }\!\!'\!\!\text{ } \\ \text{CAG}\,\text{ATA}\,\text{GCA}..... \end{smallmatrix}}{\overset{\text{CAG}\,\text{TAG}.....}{\mathop{\uparrow }}}\,\] Insertion of 'A' has shifted the reading frame. Insertion is the addition of one or more nitrogenous bases to the nucleotide chain, changing the complete reading frame.You need to login to perform this action.
