Practice D1.3 Mutations and gene editing with authentic IB Biology exam questions for both SL and HL students. This question bank mirrors Paper 1A, 1B, 2 structure, covering key topics like cell biology, genetics, and ecology. Get instant solutions, detailed explanations, and build exam confidence with questions in the style of IB examiners.
Mutations are considered random even when mutagens are present. Which of the following explains why?
A mutation changes one base in an mRNA codon from GAG to GUG. How might this affect the resulting protein?
Why must DNA replicate before a parent cell divides?
Which of the following is a type of gene mutation?
Which of the following is an example of a neutral mutation that still contributes to evolution?
Which type of mutation is most likely to change every amino acid downstream?
A patient develops colon cancer due to a mutation that disables a tumor suppressor gene. What kind of mutation is this?
A mutation deletes a single base early in a gene coding for a metabolic enzyme. It occurs in a somatic cell in the liver. What is the most likely combined consequence?
Which of the following can cause gene mutations?
Which best describes the evolutionary significance of random mutation?
