Hi everyone. Let's take a look at this practice problem together. D. N. A. From a Y plus Z. Plus bacterial strain was transformed into a Y. Z bacterial strain. The transform ints obtained whereas follows Y Z plus 100 Y plus Z. 125 and Y plus Z plus determine the co transformation frequency. So we are given two bacterial strains with the following gina types. Y plus Z plus and Y. Z. Now recall that transformation is one way that bacteria can uptake D. N. A. From their environment. And so let's draw this out. You would have a bacteria with their genome and this would be Y. Z. And transformed into it would be the Y plus Z plus genes. Now you can get mixing and crossing that occurs and then the following gino types would occur as listed in the practice problem. So we need to know what the co transformation frequency is now. What is that? It is the number of co transform ints. So those genes that are transformed together. So in our case it's Y plus Z plus genotype over the total number of transform intense. And for us that is gonna be plus 125 plus 75. And there's 300 transform. Its total. Now co transform its Y plus Z plus there were 75. So that's going to be 75 out of 300 Is gonna eat 0.25. Now our answers are all given in percentages. So we're just going to multiply that number by 100. And that's gonna give us 25%. And so a 25% is our answer. All right, everyone. I hope you found this helpful, and I'll see you for the next practice problem.
