(4 points) If the sequence shown below were used by RNA polymerase to transcribe

Question

(4 points) If the sequence shown below were used by RNA polymerase to transcribe what would the sequence of the mRNA be? Indicate the 5' and 3' ends of the mRNA strand. 6. mRNA, 3'-GACTGGAC-5 7. (6 points) If the sequence shown below were used by a ribosome to translate into a polypeptide, what would the sequence of the polypeptide be? Write your answer from let right starting with the N-terminal residue. You may use three-letter or one letter codes to indicate the identity of the amino acids. s-UGUUACAUGGAGACUCACUACCUGUGAUUU-3

Explanation / Answer

6.- The transcription begins from 3' to 5'. T becomes U because it is RNA.

5'-CUGACCUG-3'

here you can see the complementarity.

or

3'-GUCCAGUC-5',

7.- The transcription begins from 5' to 3'.

UGU= Cysteine

UAC= Tyrosine

AUG= Methionine

GAG= Glutamic acid

ACU= Threonine

CAC= Histidine

UAC=  Tyrosine

CUG= Leucine

UGA= Stop

UUU= Didn't read

Then, the peptide is:

CYMETHYL
