Describe the role of heteroduplex formation during transformation.

Video transcript

Hi, everyone. Let's take a look at this practice problem together, identify the enzyme that digests one of the strands of the transforming D N A. So we need to identify the enzyme that digests some of the transforming D N A. And recall that transformation is the process of bacteria taking D N A up from the environment. If we glance at all of our answers, they all end in the A S E and in biology, the suffix A S E is used to signify enzyme. So let's take a look at our answers. We have a like. So we have the prefix liga which means to bind. And so think of legs as binding. It's the molecular glue which links to molecules and this is the opposite of what we want. And so A is incorrect. If we take a look at sea preliminaries, it has the prefix polymer and polymer suggests building or adding and a polymer raise builds polymers of nucleic acids. And so C is not correct. Then if we look at D lies is think of license, the L Y license and license means to break down. And so option D is going to be incorrect as well. Finally, let's look at B nuclear. Yes, it begins with N U C L E. So think nucleic acids and what has nucleic acids? D N A D N A has nucleic acids. And so a nuclear days would break down the nucleic acids in D N A. So B is going to be our answer. Alright, everyone. I hope you found this helpful and I'll see you for the next practice problem.
