Question

In your lab you are studying the genome of venomous rattlesnakes to find the gene which codes for their venom glands. One rattlesnake has a mutation and cannot produce venom. You compare his DNA to a normal rattlesnake. What type of mutation has occurred?
Normal: AATCGCTACGCACGTCAG
Mutated: AATCGCCATGCACGTCAG

A. Inversion
B. Insertion
C. Point mutation
D. Deletion

Answer 1

The type of mutation that occurred here is an inversion of three nucleotide bases (Option A).

What is an inversion?

An inversion is a type of mutation where linear order of nucleotide in the mutated sequence is inverted.

In this case, we have an inversion that involves the following bases (bold highlighted) AATCGC TAC GCACGTCAG and AATCGC CAT GCACGTCAG.

In conclusion, this mutation is an inversion of the genomic sequence (Option A).
