Hey everyone. Let's take a look at this question together. Which of the following statements about whole genome sequencing is true. So what do we know about whole genome sequencing When we know that it allows the sequencing and assembling of the whole gino. And we know that it is also referred to as shotgun sequencing. And this is because multiple copies of the entire chromosome are cut into short and overlapping fragments. And we know that the whole genome sequencing process includes D. N. A. Shearing D. N. A. Barcoding D. N. A. Sequencing. And lastly it involves data analysis. And so now that we have these points about whole genome sequencing written down, let's take a look at the answer choices to figure out which of the following statements is true. Well we can see answer choice A says they can identify small numbers of genes at a time which we know is incorrect since it allows the sequencing and assembling of the whole genome, it would identify large numbers of genes at the same time. So answer choice A. Is incorrect. Answer choice B says it involves cutting DNA into smaller pieces. Which another term for this is that D. N. A. Sharing which we know that it is included in whole genome sequencing. So answer choice B is a true statement about whole genome sequencing and answer choice C. Is incorrect because we know that we do not use gel electrophoresis. So it cannot be answer choices C. Or answer choice D. And answer choice B is the only true statement here about whole genome sequencing. I hope you found this video to be helpful. Thank you and goodbye.
