mutation trivia questions
A mutation is a change in what?
Answer: Genetic material
Bonus fact: Mutations alter DNA or other genetic material.
Can mutations be beneficial, harmful, or neutral?
Answer: Yes

A mutation affecting a single DNA base is commonly called what?
Answer: Point mutation
Bonus fact: Point mutations alter one nucleotide or a very small region.

Answer: Nonsense mutation
Bonus fact: A new stop codon from a nonsense mutation usually produces a shortened protein that is likely nonfunctional.
What is a major concern when editing DNA at unintended sites?

Which condition is required for Hardy-Weinberg equilibrium?
Answer: Random mating
Bonus fact: The model assumes random mating, no selection, no mutation, no migration, and a very large population.
What term describes a change in a DNA sequence?
Answer: Mutation
