Question

On the mRNA sequence below, show what would happen to the amino acid sequence if an extra RNA nucleotide was added (you can add a base wherever you like). What type of mutation is this, and what’s the resulting amino acid sequence? U
AUGUACGUACUCUGA



.

Answer 1

That is called an insertion mutation which is a type of a frameshift mutation

depending on where you put the extra nucleotide, the amino acid sequence may look different.
