Question

What happens in a frame shift mutation when one DNA Nucleotide is inserted?

Answer 1

The DNA within a gene codes for the amino acid sequence in a protein , and so DNA mutations can lead to protein changes. The code is read in triplets, sequences of three nucleotides. From this, it is readily seen that any insertion or deletion will change the triplet groups, and so may have major effects on the amino acids coded for. This is called a frame-shift mutation. Frame-shift mutations almost always result in nonfunctional proteins.

Answer 2

This is the question we are trying to solve =)

Answer 3

I think LiliaKarina's answer should be helpful.

The end effect of a 1 nucleotide insertion is that all the reading frame for all subsequent reading frames will be shifted.

"THE" "FAT" "CAT" "SAT" becomes "THE" "FDA" "TCA" "TSA" with the insertion of an extra letter in the second 'codon.' Doesn't make much sense, does it?

Answer 4

I meant the reading frame for all subsequent codons. I have not yet had my tea this morning.

Answer 5

Thanks for the help everyone, I got the answer correct =)
