Accepted Answer

Hello and welcome. Let's look at the next question during the transcription, which DNA strand serves as the template for MRN A synthesis, a non template strand B, antisense strand C coding strand or D none of the above. Well, hopefully, we would understand that we could eliminate choice a non template strand right away since we're literally asked, which serves as a template. And it's named the non template strand since it's the one that is not. So to think about this, we'd want to think about the fact that you have your DNA strand. So you'd have your, we'll call it template strand and non template strand for now, I've rewritten those and spread them out a bit and we recall that these two strands are complementary to each other. And then when we have the template strand which is acting as a template for my MRN A strand that's being synthesized, so that underneath template strand will write MRN A, then the MRN A strand is complementary to the template strand, the one is acting as a template. So as a result, the MRNA strand is the same sequence as the non template strand since it's complementary to its complementary strand. Now, of course, we have to remember that the MRN A is going to have uracil where the DNA strand has thymine. But other than that, the order of base pairs is going to be the same. So here it just recall, needs recalling the different names you give these strands. So non dub and template is pretty straightforward, but we also call the non template strand choice c the coding strand. So the coding strand is the non template strand because since it goes in the same order as the MRN A, if you want to know, you know, what are the different codons going to be, you can look at the coding strand and look at those three letter coons and see what amino acid you will have since it's in the same order as the MRN A that serves to make those codons. So this would be the non template. So choice C coding strand is not going to be correct. So the last option here is antisense strand and this is our answer. And that's because again, if you think about sort of the area, the strand where you can read the coons that will lead to the amino acid sequence, that makes sense because you can make sense of those that sequence. So the non template strand or excuse me, the template strand is going to be antisense because its base will not be in the order of coons. So it does get a little tricky. I always find it helpful to write the three strands like this to keep straight, which ones are complementary, which are in the same order. But choice B, the antisense strand will be the same as the template strand and it's antisense because as a template, it's complementary. So it's complementary to that MRNA sequence. And therefore you can't read off the code ons from it without obviously reading it backwards. So that also limited choice T none of the above. So once again, in transcription, the DNA strand that serves as the template for MRN A synthesis is choice B the anti strand hope to see you in the next video.
