Given the following codons and their corresponding amino acids (T & I /10) UUU- Pheylalanine CUA – Leucine GCU – Alanine AAA – Lysine a) show the mRNA which codes for the short peptide, lys-ala-phe-leu. Include what should come before and after this short message. (2 ) b) Show the tRNAs that would line up at the mRNA and their anticodons (2) c) Show the base sequence that would be found in the DNA double helix which carries the gene for this peptide. Label the coding and template strand. d) What if there was a frameshift at leucine. A cytosine was inserted directly after the first cytosine (on the template strand). How would the amino acid sequence be altered? Would this alter translation? e) When the DNA was replicated which enzymes were responsible for this error?
