73 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
O (2) UAU-CGA-GGA-GUU-GCG-CUC
O (3) CUC-GCG-GUU-GGA-CGA-UAU
O (4) CUC-UUA-UUU-GUU-CGA-UAU

(2) UAU-CGA-GGA-GUU-GCG-CUC

Explanation:

The mRNA is produced by the process of transcription which transcribes the DNA to mRNA which can be recognised and read by the ribosomes.

The ribosomal subunits get attached to the mRNA which scans or read the mRNA in the form of codons or triplets of nucleotides. These codons code for particular amino acid and about 64 codons code for 21 amino acids.

In the given question, the sequence of the amino acids in the peptide has been provided based on which the sequence of codons can be easily decoded.

For the provided peptide, the sequence of amino acid will be Option-2 which is UAU-CGA-GGA-GUU-GCG-CUC as this sequence of codons has the codons arranged according to the sequence of the amino acid.

Thus, Option-2 is the correct answer.

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.
