Question

Bacterial DNA polymerase I and DNA polymerase III perform different functions during DNA replication.

Identify the principal functions of each molecule.

Accepted Answer

Hey, everyone. Let's take a look at this question together which of the following functions of DNA polymerase enzymes is true. Is it answer choice. A DNA polymerase one is required to remove the R N A primer and fill the gap with DNA. Answer choice B DNA polymerase three is responsible for catalyzing the five end to three end polymerization of DNA strengths during replication. Answer choice C, the main role of DNA polymerase two is in the repair of inners strand cross links or answer choice D all of the above. Let's work this problem out together to try to figure out which of the following statements about the functions of DNA polymerase enzymes is true. So in order to solve this question, we first must recall what we've learned about the different DNA polymerase enzymes to try to figure out which of the following statements is true. Answer choice A is talking about DNA polymerase one which we know that DNA polymerase one is an enzyme responsible for removing the R N A primer and filling the gap with DNA. So answer choice A says that DNA polymerase one is required to remove the R N A primer and fill the gap with DNA, which we know that this is an essential step N DNA replication. So answer choice A is a true statement. But before we select answer choice A as our answer, let's continue with the other answer. Choices. Answer choice B is talking about DNA polymerase three, which we note that DNA polymerase three is an enzyme responsible for catalyzing the five end to three and polymerization of DNA strains during replication. And so answer choice B which says DNA polymerase three is responsible for catalyzing the five end to three end polymerization of DNA strands during replication. It's also a true statement since that step is necessary four DNA replication. And lastly answer choice C says that the main role of DNA polymerase two is in the repair of inners strand cross links, which we know that DNA polymerase two is the enzyme mainly involved in the repair of the inner strand cross links and it is necessary or the repair of damaged DNA. So answer choice C is also a true statement which means that answer choice A B and C are all true statements about the functions of their respective DNA polymerase enzyme. Thus making answer choice D all of the above the correct answer because the function of DNA polymerase one in answer choice A is true. The fun function of DNA polymerase three in answer choice B is also true. And lastly the function of DNA polymerase two in answer choice C is a true statement. So answer choices A B and C are all correct and answer choice D, all of the above is the appropriate correct answer. I hope you found this video to be helpful. Thank you and goodbye.
