[Video] Q29: Do the data in the table support the authors’ proposed pairing of bases in dna?

Explanation for Question 29 From the Reading Section on the Official Sat Practice Test 1

Okay. So I'm 29 is referring to the graph. 2 So that, or the tables that says to the table, do the data and 3 the table support the authors propose pairing of basis in 4 DNA. So, first of all, before we even look at the table and we 5 have to know from the passage, what was the authors proposed 6 pairing of basis in DNA? Um, 7 he had said, let's see, let's go a little bit back. 8 Right. So let's see. 9 Yeah. So here we go. So this paragraph, 10 the basis are joined together in pairs, a single base from one chain being 11 hydrogen bond into a single base from another. The important point is that only 12 certain pairs of basis will fit into the structure. One member of a pair 13 must be appearing in the other pyramiding. 14 So that is what they're talking about here is that one must be appearing. 15 The others needed pyramiding. So you can't, for example, 16 have like, like these are the pyrenes and these 17 are the pyramid deans. So we can't combine like these 18 two, for example. Um, because then you'd end up having, 19 you know, two hearings versus having a one period and one, 20 um, pyramiding. Okay. So let's go back to the question now, 21 now that we kind of know what we're looking at here in terms of 22 the table, does the data support the authors proposed pairing 23 of basis in, in, 24 um, yeah, 25 in the DNA. Okay. 26 Let's see. Okay. 27 So what we're trying to look for here is basically these 28 percentages should be similar and then these percentages should be simila...
