Question

Figure 1.6 presents simplified depictions of nucleotides containing deoxyribose, a nucleotide base, and a phosphate group. Use this simplified method of representation to illustrate the sequence 3'-AGTCGAT-5' and its complementary partner in a DNA duplex.

What kind of bonds join the C in one strand to the G in the complementary strand?

Accepted Answer

Hello, everyone. And welcome to today's video. So how many hydrogen bonds hold side a scene? And one in, in a DNA duplex as answer choice A, we have one as answer choice B we have two as answer choice C we have three and as answer choice D we have or well, remember that these DNA double helix are going to have the two strands interacting with each other via hyen bonds. This is mostly how they are kept together. Now, the nature or the number of the hydrogen bonds really depends on the pairing that we're looking at. So for example, the A two T or the A to thine pairing is going to always form two hydrogen bonds. Well, the cytosine to one or the C G pairing is going to form a total of three hydrogen buns. So for every cytosine to one in pairing that we have in this DNA double helix, we're going to have three hydrogen bonds. So the correct answer choice here, since we're being asked for cytosine and one is going to be answer choice C or three, I really hope this video helped you and I hope to see you on the next one.
