Final answer:

The outcome of a new nucleotide sequence in protein synthesis depends on whether the changes affect the codons coding for amino acids. If codons are preserved or synonymous substitutions occur, the same protein will result; if nonsynonymous substitutions occur, a different protein will be produced.

Step-by-step explanation:

Protein Synthesis and Genetic Variation

The question at hand concerns whether a new sequence of nucleotides will result in the same protein or a different one. During protein synthesis, the cellular process called transcription first generates messenger RNA (mRNA), which carries a copy of the genetic code from DNA. The mRNA is then translated into a protein product during translation, which occurs in the ribosomes. Since each amino acid in a protein is defined by a three-nucleotide sequence known as a codon, a change in the nucleotide sequence can result in the incorporation of a different amino acid, potentially altering the protein's structure and function. However, it is important to note that the genetic code is degenerate, meaning some amino acids are encoded by more than one codon, allowing for certain changes in the nucleotide sequence to occur without altering the resulting amino acid.

If the new nucleotide sequence preserves the same codons or introduces codons that code for the same amino acids (known as synonymous substitutions), the same protein will result. In contrast, if the new sequence alters the codons in a way that different amino acids are specified (nonsynonymous substitutions), a different protein will result. The impact of this alteration depends on the role and location of the affected amino acids within the protein, which can lead to changes in the protein's folding, function, or activity.
