Answer 1

The primary role of transfer RNA (tRNA) in protein synthesis is carrying amino acids to the ribosome.

Answer 3

To determine the amino acid sequence corresponding to the mRNA strand provided:

1. We first need to know the genetic code, which relates specific three-nucleotide codons to amino acids.
2. The mRNA sequence provided is made of the following codons:
   • CUC
   • AAA
   • CGU

Now we can translate each of these codons into their corresponding amino acids:

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

Thus, the amino acid sequence for the given mRNA strand would be:

• Leu - Lys - Arg

If you need to input this in the response areas, you would enter:

1. Leu
2. Lys
3. Arg
