Accepted Answer

Hi, everyone. Here's our next problem. It says the base pair sequence of A coding DNA strand is given below five prime T AC G T A T C C A T C G C T C A three prime, which of the following would be the sequence of M R N A transcribed from the template strand of that DNA segment choice A five prime U ac G U A U C C A U C G C U C A three prime choice B three prime A U G C G A U C G G U ac G U ac five prime choice C five prime, U ac G U A U A G G U A G C G A G three prime invoice D three prime U ac G U A U A G G U A G C G A G five prime. So since DNA is always double stranded, we have to remember which strand the R N A is going to be transcribed from the template strand. And what order the M R N A will be going in. So we have our double strand of DNA and we have our template strand that as the name says will be used as the template for our M R N A. That means that our M R N A will be complimentary to the template strand as a result. The other strand that's not the template is called the coding strand. That can be a little confusing because it's not the one used as the template, but it has that name because it's also complimentary to the template strand. And therefore the coding strand and the M R N A strand are going to have the same nucleotide sequence except that any T in the DNA strand will obviously become a U in the M R N A strand. So with that in mind, let's look at our answer choices we've been giving, given the base pair sequence of a coding DNA strand. So that makes it easier. We're going to look for the M R N A strand that has the same sequence as the strand we're given except for the replacement of the T S. Now we do want to pay attention because some of our answer choices are given in the five prime to three prime direction, but some are given in the opposite direction. So when we're comparing strands, we want to make sure we're going in the same direction because again, we're not talking about a complementary strand which would go in the opposite direction, but one that will be the same direction. So let's start with choice A, it starts with five prime as does the strand were given. So we can start, we can go in the direction left to right. We see that our first three base pairs here are T ac, the strand we're given. So they should be U AC and the M R N A. And that is indeed what we have. What I would do on a test is make a quick glance at my other answer choices and see if I can eliminate any right away with those first three base pairs. So let's look at choice B. Now, choice B is going in the opposite direction, three prime to five prime. So I need to start on the right hand side. And when I start on the five prime side, my first two base pairs are C A U which are not correct. So we can go ahead and eliminate choice B as we know, the first three base pairs are not correct. Let's look at choice C and choice C starts in the with five prime. Its first three base pairs are also U AC. So that's a possibility as well. And then choice D runs in the opposite direction, three prime to five prime and its first three base pairs in the five prime side are G A G. So not correct. So we can eliminate choice D as well. So now we just have two of them to look at. So let's look at our next three basis we have G T A. So the corresponding M R N A should be G U A. So let's look at choice A, we do indeed have G U A here. Let's look at choice C also G U A. So let's keep going. The next three are T C C. So we should see U C C do I say that's what we have and choice C, we have U A G, So that's not correct. So we can go ahead and eliminate choice C and we have our answer as choice. A. So which of the following would be the sequence of M R N A transcribed from the template strand of the DNA segment. Given choice A U AC G U A U C C A U C G C U C A. See you in the next video.
