All right, for this problem, we're going to practice writing consensus sequences, which is essentially looking at a bunch of sequences for one set of base pairs, different organisms, different individuals, etc.
00:13
And then we're going to take what's the most common base pair at each spot, and then write our consensus sequence based on that.
00:20
So here we've got six, and we're going to write our consensus sequence underneath.
00:25
And we'll just go row by row.
00:28
And if we need to, i'll explain some different rules that we can, keep in mind if like there's a tie or different scenarios so we're going to just go for it so the first column uh we've got a a t a t so this is a tie between a and t so what we're going to do uh since a a is a purine and and t is a perimedean we can't just put a code for periens or code for perimedes we're going to say a slash because they're both equally as common.
01:07
And then for our second row, g, g, c, c, c, g.
01:12
This is another scenario, but it's the opposite.
01:15
So g and c are going to be here.
01:20
Same thing.
01:21
Can't just say perimidates, or can't we just say periods? because c is a perimeter and g as a period.
01:27
We're going to have to use both.
01:28
So c slash g.
01:31
So our third slot is g, c, g, g, g.
01:36
C c.
01:38
So again, this is going to be c slash g...
