A mutation changes one nucleotide in a gene that codes for an enzyme. What would be the most likely result?
Question 11 options:

The mutation would automatically be corrected by cellular repair mechanisms

The gene would become completely non-functional and stop producing protein

All other genes in the cell would also become mutated through chain reactions

The enzyme might have altered or reduced function due to structure changes

The enzyme might have altered or reduced function due to structure changes.

Reason: a single-nucleotide change often causes a missense mutation (one amino acid substituted), which can alter protein folding or the active site and change enzyme activity. It could also be silent (no change) or occasionally nonsense (premature stop), but automatic repair or a chain reaction mutating all other genes are not the most likely outcomes.
