HEL Which of the following statements best describes why the change in only one DNA base of a gene does not always result in a different protein being produced by the gene?

A. The change prevents mRNA from being made.
B. Some codons code for the same amino acid.
C. Some codons are translated from DNA.
D. The change creates an additional mRNA strand.

The statement which best describes why the change in only one deoxyribonucleic acid (DNA) base of a gene does not always result in a different protein being produced by the gene is: A. The change prevents mRNA from being made.

Deoxyribonucleotides refers to the fundamental (basic) unit of a deoxyribonucleic acid (DNA).

Basically, deoxyribonucleotides contains a nitrogenous base and phosphate group that is referred to as deoxyribose sugar.

On a related note, the nitrogenous base of deoxyribonucleotides includes the following components:

Gene expression simply means the transcription of a gene into a messenger ribonucleic acid (mRNA), as well as its subsequent translation into protein.

In Genetics, the genes that are present in deoxyribonucleic acid (DNA) are mainly responsible for encoding protein molecules.

However, a change in a single deoxyribonucleic acid (DNA) base of a gene doesn't always result in the production of a different protein by the gene because the change prevents messenger RNA (mRNA) from being made.

Synonym codons code a single amino acid. In consequence, 'some codons code for the same amino acid' indicates why a change in one DNA base of a gene does not always result in a different protein (Option B).

In conclusion, the statement 'some codons code for the same amino acid' BEST describes why the change in one DNA base of a gene does not always result in a different protein (Option B).
