Question

imagine a mutation changes a base in a dna sequence. explain how this could affect protein synthesis. (dok3)
it could change the amino acid sequence, because it could result in a change to the codon which would in turn change the amino acid sequence which will alter the function of the protein.
it would always stop protein synthesis completely, because a base change in the dna will always mean that the protein cant be produced or function properly.
it would have no effect on the protein produced because all mutations are silent and will not change the resulting protein.
it would only affect the cells energy production, because most of the genes in dna lead to proteins that help produce energy for the cells needs.

Explanation:

DNA mutations can change codons. Codons code for amino - acids. A change in amino - acid sequence can alter protein function. Not all mutations stop protein synthesis or are silent, and DNA mutations don't directly affect cell energy production in the way described.

Answer:

It could change the amino acid sequence, because it could result in a change to the codon which would in turn change the amino acid sequence which will alter the function of the protein.
