Final Answer:

The following question refers to this table of codons. A. met-ser-leu-ser-leu-ser will be generated, based on the following mRNA codon sequence

Step-by-step explanation:

A.The mRNA codon sequence 5' AUG-UCU-UCG-UUA-UCC-UUG 3' corresponds to the amino acid sequence methionine (AUG) - serine (UCU) - leucine (UCG) - serine (UUA) - serine (UCC) - leucine (UUG). Each three-nucleotide codon codes for a specific amino acid, and the given sequence follows the standard genetic code.

Therefore, option A, "met-ser-leu-ser-leu-ser," accurately represents the amino acid sequence generated from the provided mRNA codon sequence.

The initiation codon AUG codes for methionine, serving as the starting point for protein synthesis. Subsequent codons are read in a sequential manner, with each codon specifying a particular amino acid. In this case, UCU codes for serine, UCG for leucine, UUA for serine, UCC for serine, and UUG for leucine. Understanding the correspondence between mRNA codons and amino acids is crucial in decoding genetic information and predicting the resulting protein sequence.

In conclusion, the amino acid sequence generated from the given mRNA codon sequence follows the standard genetic code, and option A accurately represents the sequence of methionine, serine, leucine, serine, leucine, and serine. This illustrates the fundamental process of translating genetic information from mRNA to protein, where each codon determines a specific amino acid in the resulting polypeptide chain.
