DNA has two strands.
Imagine you look at one in 5′>3′ direction. You get to the primer and then start codon and the coding region etc… now, when you’ve passed the coding region you look at the other, complementary strand (and read it in the opposite direction, for that strand also 5′>3′ direction) – imagine you also find a primer and a start codon – is it possible for one of them, or maybe only coding region, to overlap with the other strand’s coding region?
If so, is there a difference in pro/eucaryots or viruses….?
I know abpout overlapping on the same strand because of frameshift, but I didn’t find any evidence in the literature about this kind of overlap….I know when you think logically it seems even less complicated for the genome to overlap in this fashion (and maybe because of this logic authors didn’t stress it) but I’d still like to be sure and have an example…
