Mutations

Biology ⇒ Genetics and Heredity

Mutations starts at 10 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Mutations. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A student is studying a gene and finds that a single base pair has been deleted. What type of mutation is this, and what is its likely effect?
Describe how a nonsense mutation can affect the resulting protein.
Describe how environmental factors can increase the mutation rate in organisms.
Describe the difference between a somatic mutation and a germline mutation.
Describe the difference between a transition and a transversion mutation.
Describe the role of DNA repair mechanisms in preventing mutations.
Explain how a base substitution can lead to a missense, nonsense, or silent mutation.
Explain how a mutation in a regulatory region of DNA can affect gene expression.
Explain the difference between a gene mutation and a chromosomal mutation.
Explain why frameshift mutations are often more severe than point mutations.
Explain why not all mutations in a gene will affect the protein product.
What is a mutation in the context of genetics?
