Question

the genetic code is based on triplets of bases(hypothesis)
a-single base substitutions affect only one amino acid in the protein chain
b-one or two bases deletion or insertion in agene disrupt its function three bases deletion or insertion are often compatible withe function

Answer 1

Answer:(b) one or two bases deletion or insertion in a gene disrupt its function three bases deletion or insertion are often compatible withe function

According to the triplet of bases hypothesis,when there is a change in a single bases then there is a change in the entire sequence and this can go beyond the site of deletion or insertion,but after the deletion or insertion in the three bases they move back to their normal functions therefore here it says they are often compatible with the functioning.
