The messenger RNA sequence that codes for the amino acid chain TYR-ARG-GLY-VAL-ALA-LEU is: (1) UAU-CGA-GUU-UUU-UUA-CUC (2) UAU-CGA-GGA-GUU-GCG-CUC (3) CUC-GCG-GUU-GGA-CGA-UAU (4) CUC-UUA-UUU-GUU-CGA-UAU

To determine the messenger RNA (mRNA) sequence that codes for the amino acid chain TYR-ARG-GLY-VAL-ALA-LEU, we need to use the genetic code, which translates the mRNA codons to specific amino acids.

Here is the genetic code showing mRNA codons and their corresponding amino acids:

UAU-Tyrosine (TYR)

CGA-Arginine (ARG)

GGU-Glycine (GLY)

GUU-Valine (VAL)

GCA-Alanine (ALA)

CUC-Leucine (LEU)

Now, arranging these mRNA codons based on the amino acids they encode, we get:

The correct mRNA sequence that codes for the amino acid chain TYR-ARG-GLY-VAL-ALA-LEU is: (1) UAU-CGA-GGU-GUU-GCA-CUC
