WebJul 26, 2024 · Right now, I have a semi-automated way of generating the mutations. It now generates the vector without me typing them all out, but only works for 8 nucleotide long sequences. There has to be a better way to generate the vector for any nucleotide sequence of any length. This is my code: Web1 Answer. At each base, you can have 4 different bases (A,T,C or G). Therefore for the first base there are 4 possibilities, namely.
