Hi everyone, Welcome back, let's look at our next question. It says blank is necessary for DNA replication, since it separates double stranded DNA into single strands, allowing each strand to be copied. So we are looking for the enzyme. We stare for answer choice for all enzymes that separates the double stranded DNA two single strands. Well in that case we're looking for Choice C, which is hell a case, we remember the word helix so he'll cases that enzyme that opens up the double helix, allowing each of the strands to be copied. But let's just look briefly at our other answer choices to be thorough here. Choice A. Is D. N. A. Preliminaries, but that's not correct because that's what adds bases on to synthesize the new strand. So it's not what separates the two strands, although it is necessary for DNA replication, but not because it separates double stranded DNA. So that's why that's incorrect. Choice B is DNA legs. Legs is also necessary for DNA replication, but it doesn't separate strands. DNA legs is responsible for joining the Okazaki fragments on the lagging strand so necessary necessary for replication but not because of the the mechanism mentioned in the answer in the question. So, Choice B is incorrect. And finally, Choice the primates primates is what adds the RNA primer that's needed for DNA replication to start. So that DNA prelim race starts working from an RNA primer that binds to that, that DNA once it's been opened up by the case, so necessary, but again, not for the reason. And the question, So choice D is not correct. So Choice C. Healy case is necessary for DNA replication, since it separates double stranded DNA into single strands, allowing each strand to be copied. See you in the next video.
