Question

15. Use the chart below to determine the amino acid sequence of the following strand of mRNA.

mRNA strand: AUGAAGGGCUGA
Amino Acids:

Answer 1

should be : UACUUCCCGACU

Answer 2

In order to read the information from a copy of mRNA, we need to read three bases one at a time. This set of three bases is called as a codon and each codon is specific for a particular amino acid. Let's put a gap between the codons, so that we could read them easily and find the respective amino acid.

mRNA strand: AUG AAG GGC UGA

amino acids: Methionine Lysine Glycine STOP codon

So there are three amino acids and one stop codon, which is like a signal for the cell to stop translation.
