Answer the following questions for the given section of DNA:

b. Using the new strand as a template, write the mRNA sequence.

Accepted Answer

All right, hello everyone. So this question says using the new strand as a template, write the Mrna sequence. So here we have two strands of DNA, one was labeled the parent strand and the other, the new strand. And underneath the new strand, we have a sequence of MRN A whose nucleotides haven't been filled yet. So first and foremost, recall that during a process known as transcription, we have the conversion of a DNA strand into a molecule of Mr N. So from there, the MRN A is used as a template during a process called translation where proteins are going to be synthesized in a ribosome. So there are two different ways of finding an MRN A sequence given the original DNA. The first is to just use the complementary base rules or the rules of complementary base pairing to go ahead and find the nucleotides of the Mrna strand based on what is complementary to the template strand. The other approach is to recall the fact that the MRNA sequence is going to resemble the coding strand. So just to go ahead and clarify right, the new strand is being treated as the template, which means that the new MRN A molecule is going to be complementary to the new strand. The parent strand, on the other hand can be called the coding strand. And so the MRN A sequence is also identical to the coding strand except for using uracil in place of thymine because this is RN A. So with this in mind, right, recall first and foremost what the base pairing rules are. So because this is MRN A, because this is RN A, we're going to use uracil instead of thymine. So Adenine is pairing with uracil and vice versa. And cytosine is pairing with guanine and vice versa. So starting off with the new strand, right, the first three bases here, first three nucleotides are T A and G according to our rules here, the first three nucleotides of the MRN A should be A U and C recall that thymine also pairs with editing, but you won't see thymine on an MRN A strip moving on to the next set of three nucleotides. We have CC A which would result in GGU on the MRN A last but not least we have TT G which would give a AC on the MRNA strand. So now we have the complete sequence, but I do just want to point out that the correct answer could have also been determined by simply copying the parent or coding strand in this instance and simply replacing thymine with your cell. Both methods methods will give you the correct answer, which is a uggua a and there you have it. So with that being said, thank you so very much for watching. And I hope you found this helpful.
