Chapter 14, Problem 1

In this chapter, we focused on the genetic code and the transcription of genetic information stored in DNA into complementary RNA molecules. Along the way, 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 were the specific sequences of triplet codes determined experimentally?

Video transcript

Welcome back everyone. Here's our next question. It says how many code owns will be generated if the genetic code is thought to be a combination of two nucleotides. So to do that, you need to calculate how many different combinations would be possible if you had just two nucleotides making up those cardigans. And there's a formula you can use, which is that the number of code owns in this circumstance would be the number of bases raise the power of the number of bases in the code on. So since we have four DNA bases and in this particular example we have two bases in each coat on, it would be four squared which equals 16. So if there were only two bases in the code on, we'd only have choice C. 16 possible combinations, which of course isn't enough for our 20 different amino acids. So that's why our codes have to be three bases bases long, otherwise we wouldn't have enough letters in that alphabet of our genetic code. So again, how many codes will be generated at The genetic code is thought to be a combination of two nucleotides. Choice C. 16 C. In the next video

From the explanations given in the chapter, what answers would you propose to the following fundamental questions: Why did geneticists believe, even before direct experimental evidence was obtained, that the genetic code would turn out to be composed of triplet sequences and be nonoverlapping? Experimentally, how were these suppositions shown to be correct?
