The agricultural research facility during a research accidentally changed the DNA sequence of a wheat plant from GCCATGTT to GCGTACTT and this mutation resulted in a stronger plant variety. What kind of mutation did the plant undergo?

GCCATGTT

GCGTACTT

C --> G
A --> T
T --> A
G --> C

all of these are transversion (pyrimidine changing to purine)

substitution

The plant undergone a mutation known as a substitution mutation. In this case, there was a substitution of one nucleotide base for another within the DNA sequence. The original DNA sequence GCCATGTT was changed to GCGTACTT, where the third nucleotide base T was replaced by C. This is a specific type of substitution mutation called a point mutation, because only a single nucleotide base was affected.
