Question

One of the possibilities considered about the genetic code was that the code was overlapping, meaning that a single base could be part of up to three codons. How many amino acids would be encoded in the sequence 5′-AUGUUACGGAAU-3′ by a non-overlapping and a maximally overlapping triplet code?
a. 4 (non-overlapping) and 16 (overlapping)
b. 4 and 12
c. 4 and 10
d. 12 and 4

Accepted Answer

Hello everyone. And in today's video we have a fairly simple problem. So let's jump straight into it. How many amino acids can be encoded by RNA with the sequence five prime. As we see here. Three prime and we have a certain number of amino assets as answer choices. Now before we jump into a problem I want you to understand just two very important facts about translations are going to help us solve this. And the first fact is that every three base pairs we get one amino acids. So for example if we have this this first three base pairs will get to one amino acid and so on. So remember that. And then we have as point to that if we reach a stop code on, translation will stop. Let me highlight that for you now. Why is that important? Because if we reach any of these cones or if you reach any of these base pairs that we see here, translation will stop this will not create an amino acid. It would just stop the translation process. So keep that in mind as we're identifying just base pairs and um you know assets. So let's begin we have that these first three Base first are going to yield one amino acid. The second three are going to yield another one. This second three are going to yield another one. These other three are going to yield another one. So we have four so far. However this last Code on which is UKA. As we see here is a stop code on so we have reached a stop code on where phenomenal asset will not be produced, and instead translation will stop. So up to that point we were able to produce four amino acids in total, so I will be the final answer to a question which we will highlight here. Answer choice. C. I really hope this video helped you and I will see you on the next one.
