Question

What is the sequence of a peptide based on the mRNA sequence 5' UUUUCUUAUUGUCUU 3' ?

a.leu-cys-tyr-ser-phe
b.cyc-phe-tyr-cys-leu
c.phe-leu-ile-met-val
d.leu-pro-asp-lys-gly
e.phe-ser-tyr-cys-leu

Answer 1

The peptide sequence based on the mRNA sequence 5' UUUUCUUAUUGUCUU 3' corresponds to E. Phe-Ser-Tyr-Cys-Leu. The mRNA codons are translated to these specific amino acids, which form the peptide chain.

Step-by-step explanation:

The student asked about the sequence of a peptide based on a given mRNA sequence. In the mRNA sequence provided (5' UUUUCUUAUUGUCUU 3'), each set of three nucleotides corresponds to a codon that specifies a particular amino acid. Using the coding table provided, we can determine the amino acids as follows:

• 
  
• 
  
• 
  
• 
  
• 
  

As a result, the sequence of the peptide would be Phe-Ser-Tyr-Cys-Leu.
