Gene Regulation, Mutation & Biotechnology — Drills · Grade 10 Science
Chapter: DNA, Inheritance & Gene ExpressionWhat these drills covers
By the end of Gene Regulation, Mutation & Biotechnology you should be able to:
- I can connect changes in DNA or regulation with possible protein effects.
- I can evaluate a biotechnology claim using evidence and limitations.
2 questions, written answer, each with a worked explanation.
Vocabulary used: mutation, regulatory sequence, genetic engineering.
Problem 1
Why can a DNA change be real while a claimed benefit remains uncertain?
Answer and explanation
Sequence confirmation does not alone establish expression, phenotype, environmental performance, or tradeoffs.
Problem 2
Trace a testable chain from a regulatory change to a trait.
Answer and explanation
Regulatory change → changed RNA production → altered protein amount → changed cellular process → measured trait; test each link and alternatives.
