Hello everyone and today we'll be discussing base pair ratios for dna.
00:07
So d &a base pair ratios.
00:23
Specifically, if we have a certain percentage of one base, how will that relate to another? so for instance, if we have 30%, don't like how thin this panel.
00:42
30 % guanine what percentage of the basis of the dna will be adenine? so according to chargoth's rule bargoth pretty sure that's how you spell his name.
01:06
According to chargoth's rule the pyramidines and the purines must have the same amount.
01:15
Must be a one -to -one ratio.
01:18
So that ultimately means that the amount of a, the amount of a base pairs, must correlate to the amount of t -based pairs, and the amount of g must correlate or be equivalent to the amount of c.
01:36
So these must equal one another.
01:41
Oh, that's really bad.
01:43
Okay, these must equal one another because they're paired together.
01:49
In base pairs of a dna like so.
01:52
You'll have your helix here, and the bases will be if a g is on this side, a c is on this side, if an a is on this side, a t will be on this side.
02:04
So they have to be equal.
02:06
Therefore, if g and c are equal, that means that g, being 30%, must equal c, which would also then be which would also then be 30%.
02:25
So given this, we know that these two are equivalent to each other...
