Question

which scenario could be the result of a single nucleotide change in the coding sequence of dna?
the amount of gene expression could change.
the protein controlled could be produced at a slower rate.
the protein could be produced in a different tissue.
the function of the protein could change.

Explanation:

A single nucleotide change (point mutation) can impact gene expression levels (e.g., affecting regulatory elements in coding regions), slow protein production (e.g., altering ribosome binding or mRNA stability), change tissue-specific production (if the mutation affects a coding region that interacts with tissue-specific factors), or modify protein function (e.g., missense mutations changing amino acids critical for structure/activity). Thus, all scenarios are plausible outcomes.

Answer:

All options (The amount of gene expression could change., The protein controlled could be produced at a slower rate., The protein could be produced in a different tissue., The function of the protein could change.) are possible results of a single nucleotide change in the coding sequence of DNA.
