Accepted Answer

All right. Hello everyone. So this question is asking us to determine which of the following correctly describes DNA replication. And here we have four different answer choices labeled A through D which we'll read individually later on in this video. But for now, let's just give some context, right? What is DNA replication and how does it happen? Well, first and foremost, recall that DNA replication is a semiconservative process. So first, let's take one strand of DNA. So here's my double stranded DNA. And so the first thing that happens is that these two strands of DNA are first separated from each other. Once they're separated from each other, they can be used as templates to create new strands of DNA, right? So from here, DNA polymerase can attach to both strands and produce the complement of each template strand resulting in two new DNA molecules or two new double helices, I should say. So that's my little scheme here representing the process of DNA replication. Now, of course, the sizes aren't to scale. But the main point is really just to showcase that one double stranded DNA, one molecule of double stranded DNA can be used to produce two new double stranded DNA molecules. So with this in mind, let's start by reading option A which says that this is the process in which the double helix structure of DNA is unwound. This is true, right? Because as mentioned before, the original double helix structure of DNA has to be unwound. First, the two strands have to be separated from each other. So that each one of them is used as a template for a new double stranded DNA molecule. Option B on the other hand says that this is the process in which DNA information is used to transfer genetic information and this is incorrect, right? Because what does it mean for DNA information to be used to transfer genetic information? Well, recall that oftentimes RN A is used to transfer genetic information because RN A then codes for a protein. So the process by which DNA is converted into RN A is known as trans transcription, excuse me, transcription is of course not DNA replication. So option B is not correct. On the other hand, option C here says this is the process of linking amino acids together using information from segments of DNA. So here, right, for option C, the process of linking amino acids together means that proteins are being synthesized. And if you recall during the process of translation RN A, which is obtained from DNA is then used to produce a protein. So C is talking about translation and last but not least, option D says this is the process in which DNA is synthesized using an RN A template. So going back to our discussion on transcription, we said the transcription is when DNA is converted into RN A. So option B is talking about the opposite, right. We're taking RN A and making DNA. So this is reverse transcription, not DNA replication. So all this is to say that our correct answer is going to be option A in the multiple choice and there you have it. So with that being said, thank you so very much for watching and I hope you found this helpful.
