Question

translation:
level 1: use the codon chart to identify
the amino acid that goes with the
following mrna codons:
uuu= phe
cug= leu
aug= met
uga= stop
(write the amino acid as the three letter
abbreviation...ex: met, val, leu)

level 2: where does translation take place?
what is made at the end of translation?

(the codon chart is presented with rows and columns labeled by first and second letters of codons, showing corresponding amino acids or stop signals.)

Explanation:

Step1: Analyze UUU codon

Check the codon chart. For UUU, first letter U, second U, third U. The chart shows UUU (and UUC) correspond to Phe (Phenylalanine).

Step2: Analyze CUG codon

First letter C, second U, third G. In the chart, CUU, CUC, CUA, CUG all correspond to Leu (Leucine).

Step3: Analyze AUG codon

First letter A, second U, third G. The chart shows AUG corresponds to Met (Methionine, also start codon).

Step4: Analyze UGA codon

First letter U, second G, third A. The chart shows UGA is a Stop codon.

Step5: Level 2 - Translation location

Translation occurs at the ribosomes (in the cytoplasm, on rough ER).

Step6: Level 2 - Product of translation

At the end of translation, a polypeptide chain (protein) is made by linking amino acids.

Answer:

Level 1:
UUU = Phe
CUG = Leu
AUG = Met
UGA = Stop

Level 2:
Where does translation take place? Ribosomes (in the cytoplasm)
What is made at the end of translation? Polypeptide (protein)
