Question

what should be the third amino acid in the protein translated from the mrna sequence below? augaggcccguug...

Explanation:

Step1: Divide mRNA into codons

The mRNA sequence is AUGAGGCCCGUUG... Codons are triplets of nucleotides. So, the codons are AUG, AGG, CCC, GUU...

Step2: Find the third codon

The third codon is CCC.

Step3: Look up the amino - acid for CCC

Using the codon - amino acid table, for the codon CCC (first letter C, second letter C, third letter C), the corresponding amino acid is proline.

Answer:

proline
