Chapter 20, Problem 1

In this chapter, we focused on the analysis of genomes, transcriptomes, and proteomes and considered important applications and findings from these endeavors. At the same time, we found many opportunities to consider the methods and reasoning by which much of this information was acquired. From the explanations given in the chapter, what answers would you propose to the following fundamental questions?

How has the concept of a reference genome evolved to encompass a broader understanding of genomic variation in humans?

Video transcript

Hey, everyone, let's take a look at this question together which of the following statements about human genome reference sequence is false. So let's recall what we've learned about the human genome reference sequence to figure out which of the following statements is false. So we know that the human genome reference sequence is the D N A sequence that is considered a representation or the standardized model of the human genome. And we also know that it is not the exact D N A sequence of every single person as each person has their own genetic variation. And we also know that it is a Hap Lloyd sequence, Which means that each chromosome is represented once. So we have 23 in total. And lastly, the sequence is not fixed and is periodically updated and it is periodically updated or errors and ambiguities. So now that we know this about the human genome reference sequence, which of the following statements is false. We'll answer choice. A says that it is considered the representation of the human genome, which we know is a true statement because it is a representation or standardization of the human genome. Answer choice B says it is the exact DNA sequence of each single person, which we know is false because it is not the exact DNA sequence of every single person because each person has their own genetic variation. So answer choice B is a false statement about the human genome reference sequence and it is the correct answer. And lastly, we know that answer choices C and D are all true statements because it is composed of that happily sequence and periodically updated because we know that it is a happily sequence and it is not fixed and periodically updated for errors and ambiguities. So answer choice B is the only false statement here about the human genome reference sequence. And it is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
