Question

Which genetic mutation would cause the most dramatic change in the genetic make-up of an individual?
Answer







A base-pair substitution mutation where one base pair becomes another but codes for the same amino acid








A gene mutation that inserts one extra base pair into the genetic sequence








A mutation that deletes three consecutive base pairs from the genetic material








A single point mutation that changes the codon for a different amino acid

Answer 1

It helps if you tell us which aspect of the question you, well, have a question about...

Answer 2

Well, the insertion of a base pair would cause the greatest change in the resulting protein. Most likely, it would not be able to function properly.

Answer 3

Specifically, it would cause a "frame shift" mutation. Almost always, frame shift mutations lead to a premature stop codon and a truncated protein...
