GRE Subject Test: Biology › Genetic Sequences, Transcription, and Translation
An error occurs during DNA replication, resulting in the insertion of a base pair. Replication of the original 3' DNA strand (template) produces a mutant 3' strand (mutant), as diagrammed below:
Template
3' - AUGGCCATTTTTATA - 5'
Mutant
3'- AUGCGCCATTTTTATA - 5'
Of the answers below, which best describes the type of mutation depicted above?
