Question

How do covalent bonds differ from hydrogen bonds? Define base complementarity.

Accepted Answer

Hello, everyone and welcome to today's video. So the term blank refers to a pair of complimentary DNA basis that work together to produce the run of the DNA ladder as answer choice A we have primer B is base pair C is DNA duplex. D is the initiation complex. So in order to solve this problem, we're going to go over each of the answer choices that were presented here to select the correct one. Let's begin by answer choice. A well, this is going to be primers. Well, remember that primers are going to be these R N A molecules involved in rep in replication of DNA. The question states that these are complementary DNA basis. So we're going to cancel this out, then we have the DNA duplex and the DNA duplex is going to be the DNA molecule, but it is going to be the whole molecule with double strength created when the two strands that make the DNA helix form hydrogen bonds that connect them together. So it is not referring to the complementary DNA basis that make up the DNA rather the whole molecule. And because of this, we're going to cancel it out then we have the initiation complex and this is mostly made up of R N A and is involved in translation. Again, know what we're looking for. So we're going to cancel it out and then we have a base pair. So the term base pair such for example, A and I and cytosine and refers to a pair of complementary DNA bases. This is true that work together to produce the wrong of the DNA ladder. Well, remember that these base pairs are two nuclear bases connected together by hydrogen buns such as the examples that we provided earlier. And these are going to contribute to the folded shape of both DNA and R N A and serve as the building blocks of the DNA double helix. This is exactly what the question is asking for and we're going to use it to fill in the blank. So answer choice B base is the correct answer to this question. I really hope this video helped you and I hope to see you on the next one.
