If you still have a gap and need more sequence data, then use an internal primer. WebAssume that we have two alleles at a single locus, call them A 1 and A 2, where A 1 can mutate to become A 2, and A 2 can undergo the reverse mutation to become A 1. Let A 1 mutate to A 2 at a frequency of u per generation. We will call u the forward mutation rate. Let A 2 mutate to A 1 at a frequency of v per generation. We will call v the ...

Biology Notes on Reverse Mutations Genetics

WebFor the forward strand, this means reading left-to-right, and for the reverse strand it means right-to-left. A gene can live on a DNA strand in one of two orientations. The gene is said to have a coding strand (also known as its sense strand ), and a template strand (also known as its antisense strand ).
