This is the original strand of DNA: ATG AAG TTT GGC TAA. Which option would represent a frameshift mutation due to INSERTION MUTATION?

The frameshift mutation occurs when one or more nucleotides are inserted into the original DNA sequence. In this case, let's say the nucleotide "C" is inserted between "A" and "G" in the original strand.

The modified DNA sequence with the frameshift mutation would be:
ATC GAA GTT TGG CTA A

Here, the insertion of the nucleotide "C" shifted all the subsequent nucleotides by one position, causing a frameshift mutation.
