Question

A bacterium undergoes mutation caused by an antibiotic. Specifically, the gene with the sequence AUGCCCACCCGA undergoes a frameshift mutation. Which of these sequences represents the mutated gene?

Answer 1

A. AUGGCCACCCGA

B.AUGACCCACCGA

C.AUGCCCUCCCGU

Answer 2

Specifically, the gene with the sequence AUGCCCACCCGA undergoes a frameshift mutation. what sequences represents the mutated gene?

==
This isn't a very good question. If we're talking about gene sequences, we should be given a sequence of DNA, not an RNA.

I think the desired response is this one:
B.AUGACCCACCGA
It has an insertion of an A after the first G.
But later on, the frame is restored by a deletion of a C right before the second G.
