Question

If the sequence of DNA in Question 12 were amplified using 25 PCR cycles, then the amount of this DNA would be predicted to increase by           -fold.

Accepted Answer

Welcome back. Here's our next question. Where was the name polymerase chain reaction derived from? So here we recall. We're talking about the technique of pcR which is used to produce identical oops identical copies of a desired piece of DNA. And the reactions that are used to do this take place in a chain. Uh take place in a chain form. So so let's look at our answer choices and we see that choice D. Is both A and B. So we have the possibility that both of those are correct. So choice A says it is based on D. N. A polymerase ation. That is correct. Um You have a primer that binds to the source D. N. A. And D. N. A polymerase that extends the D. N. A strand from that primer. So it is based on DNA polymerase ation. Thus preliminaries. So we're gonna put a little dot since both A and B can be correct Choice B says DNA polymerase ation takes place in chain reactions. Yes, that is true. You have repeated cycles of this, so B is also correct. Choice C. So we can actually automatically because A and B are both correct. We can. If we're on a test we could say yes, must be both A and B. Because there is no choice for all of them being correct. But we're going to be thorough here and look at choice C. Choice C says it uses the thermo cycler. Well, it is true that these days everything is automated and you do use a thermo Cycler. But when it was first invented, it was done manually. There was no Thermo cycle. So since we're talking about where was the name derived from the Thermo Cycler wasn't involved in the beginning. So choice C. Is not our answer. Both A and B. Are correct. Your choices D. Both A and B. See you in the next video.
