Question

Choose all of the following properties that indicates RNA pre-dated both DNA and proteins.

a) RNA has the ability to catalyze chemical reactions

b) RNA is extremely stable

c) RNA can fold into complex 3D shapes

d) RNA can store information

e) RNA is more complicated to make than DNA

Accepted Answer

Okay. So, this says, choose all of the following properties that indicate RNA predated DNA and proteins. So, let's go through these together and ask sort of yes or no questions. Is this a property of RNA that allowed it to predate DNA proteins? So, the first says that RNA has the ability to catalyze chemical reactions. So, does RNA have the ability to do this? Yes, it does. So, a is one of the reasons that we think that RNA predated DNA because it does have the ability to catalyze these reactions. B says, RNA is extremely stable. Well, is RNA stable? I mean, it it is semi stable, but not as stable as DNA and not as stable as proteins. So, this is not a property. So, b is not one of these, one of the answers. C says, RNA can fold into complex 3 d shapes. Well, does this happen? Right. Yes, it does happen. And, it is one of the reasons that we believe that RNA predated DNA and proteins. D says, RNA can store information. Well, we know RNA stores information through mRNAs or micro RNAs or different types of RNAs that we have today. So, D is true. RNA does have the ability to store information, and that is a requirement for life. And, therefore, it is one of the reasons we think it predated DNA. And, finally, e, RNA is more complicated to make than DNA. Well, this is not true. Deoxyribose is more complicated to make than ribose, making DNA more complicated than RNA. So e is not the answer. So the answers for this practice problem are a, c, and d. So let's move on.
