Question 10: Using the figure below, what would be the amino acid sequence for the strand of mRNA that follows:
mRNA sequence: CUC AAA CGU.

To determine the amino acid sequence, you would look at a genetic code chart or table. Based on the given sequence:

• CUC codes for Leucine (Leu)
• AAA codes for Lysine (Lys)
• CGU codes for Arginine (Arg)

Response for Question 10: Leu, Lys, Arg.
