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 11
A deletion mutation removes two nucleotides from a gene. What type of mutation is this likely to cause?
A DNA sequence changes from ATG to ATA. If ATG codes for methionine and ATA codes for isoleucine, what type of mutation is this?
