The right answer is 3 nucleotide bases.
5'-CGGCACCGCCCTAAGTCTCT-3'
5'-AGGCACCGCCCTAAGTCTAC-3'
It would be necessary first to align the two sequences side by side so as to be able to compare them, and they should also be in the same direction.
The nucleotides marked in bold are the nucleotides that differ between standard and O. Kisutch.
These nucleotide changes are necessarily due to substitution mutations that exchanged one nucleotide for another in the same location.
