So our question, which statement best describes how watson and crick's model used other scientists work to create a model of dna? so watson and crick made the first full model of dna, but they did not do it alone.
00:14
They used other scientists work.
00:16
So we're going to see which statement best describes that.
00:19
First one, chargaff's.
00:20
They use chargift rule to determine that it contains ribose sugar.
00:24
That one is not right.
00:27
Chargaff came up with the base pair rule.
00:34
That in dna, a's and t's go together and c's and g's go together.
00:41
They used franklin's photo to determine that dna was a double helix.
00:46
So far, this one seems like the correct answer because franklin did get a picture that showed that dna was a double helix, but we should still always look at the rest of our answers.

The use levine's work to determine the number of base pairs in each strand...
