Question

The bacteriophage genome consists of many genes encoding proteins that make up the head, collar, tail, and tail fibers. When these genes are transcribed following phage infection, how are these proteins synthesized, since the phage genome lacks genes essential to ribosome structure?

Accepted Answer

Everyone. Let's take a look at this question together. The following are the five steps in the T four bacteriophage is life cycle. However, the order is incorrect. Therefore determine the correct order. So let's take a look at an image depicting the life cycle of a. T. Four bacteriophage. To figure out what the correct order of the following steps is for that T four bacteriophage is life. So here we can see the life cycle of A. T. Four bacteriophage. So let's try to figure out what is happening in step one. So in the first step we can see that we have our host chromosome and we have our bacterial fage which is attached to the bacterial host cell which is a process called absorption where the bacterial phage lines to the host cell. So that would mean that the first step is that the fage is a door to the bacterial host cell which is step two. Next we can see that the host chromosome is broken down and that the bacteriophage injects its DNA into the bacterial host cell which means that's the second step of the life cycle of the bacterial fage is number three. Next we can see that the bacteria phages D. N. A. Is actually replicated and we can see some synthesis of proteins inside of that bacterial host cell. Which means that the third step of the life cycle of a bacteriophage is number one. The fage D. N. A. Is replicated, followed by the synthesis of protein components and so neck. We can see that we have all of our components connected all of our components assembled, which means that we have mature fage is assembled in the next step, which means that four is the next one. And then, lastly, we can actually see that the host cell has LISZT and those bacteria phages are being released outside of the cell, which mean the last step in the life cycle of a bacterial fage is step five, which we can also figure out by the process of elimination since we have used all the other four steps listed above. And so that would make answer choice B. The correct answer Because answer choice B has all of the steps in the T. Four bacteriophage is lifecycle in the correct order, Which we can see in this image depicting that life cycle of the T. four bacteriophage. So answer choice B is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
