Question

a strand of mrna containing the repeating sequence aag aag aag aag could code for which of the following amino acid sequences? ser - ser - ser - ser glu - glu - glu - glu lys - lys - lys - lys arg - arg - arg - arg

Explanation:

In the genetic code, each set of three nucleotides (codon) in mRNA codes for a specific amino - acid. The codon AAG codes for the amino - acid lysine (lys). Since the mRNA sequence is AAG AAG AAG AAG, it will code for a sequence of lysine amino - acids.

Answer:

lys - lys - lys - lys
