A cell begins to produce a new type of protein. This is most likely due to an alteration of the

nucleotide sequence of its template DNA strand

Explanation:

If a cell begins to produce a new type of protein, it is most likely due to an alteration of the nucleotide sequence of the template DNA strand of its genome.

The alteration of the nucleotide sequence (mutation) of the template DNA strand leads to a corresponding change in the codons of the mRNA transcribed from such DNA. A change in the mRNA codon leads to a change in the amino acid translated from the mRNA codons.

Amino acids are monomers of proteins and as such, a new protein results from altered DNA sequence.

A cell begins to produce a new type of protein. This is most likely due to an alteration of the sequence of bases in a section of a chromosome.

Explanation:

The DNA is deoxyribonucleic acid and carry genetic info for the cell. Chromosomes are made up of genes and they determine which trait that each offspring will have

DNA controls the production of protein in the cells and is the responsible part of the chromosomes for the synthesis of them. The process of protein synthesis is known as translation. An alteration in the DNA results in an alteration in the mRNA because it decides the kind of protein will be synthesized in the body. With a different message, the rybosomes the protein composition will change and a new type of protein will be synthesized.
