So today's question basically asks, you know, the following ratios or relationships would be true for a double -stranded dna molecule.
00:18
And the more you look at the answer choices, the more you have to think, well, how do i solve this kind of question? let's try to take up the easy ones out.
00:34
Option b says a plus t and then says t plus c that's wrong because you need g option g you know puts a over g and then c over a there's no t let's take that out so another one actually is where it's pairing so a plus c g plus t and then here you got a plus t g plus c and i hear you got a plus t g plus c and i option a, e having a plus g over c plus t, and then d you have a plus t, c plus g.
01:22
Now, and then, like, let's try to figure out, because this can be a little bit confusing, let's try to do, you know, treat this like we're going to convert something from sign to cosine to tangent, but with our dna, based pairs.
01:48
Let's do option f, a, c is equal to g .t.
01:58
Now, you got them being able to go together, but the major problem with that, with that kind of answer, is that you would have to divide by the a, and then if you did it by variables or numbers, let's say how much amount, here to here you have of a to g that's basically the problem with this uh with this answer is basically the entire it's just mathematically wrong so you can't you can't do that do it like that in proportion or you can't answer it like that mathematically it's just impossible so option an f is wrong.
03:06
Option d, let's try to test that out.
03:09
A plus t, is equal c plus g, is equal to 1 over 0.
03:20
Well, now that, you know, the base pairs are together, how exactly, what exactly would make this correct or wrong? well, the major problem is, again, proportional.
03:39
But if you were to split it apart like this and let's say you were to substitute it for numbers it's just not going to work so to make our answer correct and because the following question it does ask which of these is the correct ratio there has to be like a pattern so now don't we know i believe we said option d was also incorrect.
04:33
Let's try to figure out if option a or c is correct.
04:38
I believe the major problem with option a is that if you were to just try to take it out, subtract it, or anything like that, you'd be going to wrong pairs.
04:56
So that is wrong.
04:57
So now we have three answers left.
05:12
So we have option c, e, and h.
05:16
Let's try to do it.
05:20
Plus c equals g plus t...
