A portion of a polypeptide contains the amino acids Trp-Lys-Met-Ala-Val. Write the possible mRNA and template-strand DNA sequences. (Hint: Use A/G and T/C to indicate that either adenine/guanine or thymine/cytosine could occur in a particular position, and use N to indicate that any DNA nucleotide could appear.)

Hello, everyone. Here we have a question asking which of the following nucleotides is not present in RNA. And our answer is D C I mean, and it is not present in RNA because it requires more energy to produce. This is because I, I mean is a methylated version of the RNA based, you're a seal to add the methyl group requires energy. You're still is less stable than timing though. So it is easier to degrade. This is okay though because R N A is short lived compared to D N A. So errors do not cause long term damage. Thank you for watching. Bye.
