Question

Discuss the reasons proteins were generally favored over DNA as the genetic material before 1940. What was the role of the tetranucleotide hypothesis in this controversy?

Accepted Answer

Hello everyone and welcome to today's video. So which of the following is not a characteristic of genetic material? So I want you to think about from previous videos, what genetic material is going to be genetic material is or some examples of it, our DNA and RNA. So now what are some characteristics of DNA and RNA? So for example, DNA is very stable because it has to store genetic information. So answer choice A is a correct statement. Since we're looking for something that is not a characteristic, we're going to cancel this out. Then we have see it should be able to both store and express information, all genetic material in the form of DNA stores the information. And then we use R N A in order to express it, this is a true statement as well. So we're going to cancel it out. We have the issue to be able to change with mutations and variations. So DNA mutations are these changes to the genes of DNA due to many different reasons such as radiation, this happens to D N A, it happens to genetic material. So this is a correct statement as well and we're going to cancel it out and then we have the, it should not be replicable. Well, remember that D N A replication is a method by which we can replicate DNA strands. So these DNA strands are in fact going to be replicable because of this. This is going to be an incorrect statement and we're going to highlight it something that is not a characteristic of genetic material. I really hope this video helped you and I hope to see you on the next one.
