Question

Given below is a sequence of bases in mRNA of a bacterial cell. Identify the amino acid that would be incorporated at codon position 3 and codon position 5 during the process of its translation.
3' AUCAGGUUUGUGAUGGUACGA 5'

Options

• Phenylalanine, Methionine

• Cysteine, Glycine

• Alanine, Proline

• Serine, Valine

Answer 1

Phenylalanine, Methionine

Explanation:

3' AUCAGGUUUGUGAUGGUACGA 5'
↑	↑
Position	Position
3	5

Codons UUU and AUG represent the amino acids phenylalanine and methionine, respectively. Therefore, during the process of translation, the amino acids phenylalanine and methionine would be merged at codon positions 3 and 5, accordingly.
