Question: What would be the base sequence of RNA after transcription occurs? Turn this in.

Response: Transcription always goes from 5' to 3' ON THE NEW STRAND BEING TRANSCRIBED -- never the other way around. Also, remember that RNA does not have T, but has U instead. Therefore, the mRNA would be:


Question: Using the mRNA that you transcribed above, use the genetic code table to determine the resulting amino acid sequence?

Response: Translation goes from 5' to 3' as well. Therefore, we read the transcript 3 bases at a time. Each triplet makes up a codon. Then, we look up the codons on the Genetic Code table to find out the corresponding amino acids. The first triplet, i.e. codon, is AUG. This is the initiator codon which always goes for methionine. It starts all translations. The last codon, UGA is a stop codon. It ends the translation process.

So, I've broken up the transcript showing the codons clearly.


Looking each codon up in a table of the Genetic Code yields the following peptide:


Question: For each of the two, you will need to first transcribe the mRNA, and then use the genetic code table to determine the amino acid ...

Solution Summary

The base sequence of RNA is determined.
