A clear understanding of the process will help in accurately answering questions and demonstrating knowledge.
Understand the principles behind gel electrophoresis
Be able to explain how DNA fragments are separated and the significance of size in forensic applications.
A clear understanding of gel electrophoresis is essential for answering questions related to genetic fingerprinting and its applications.
Use clear examples in your answers
When explaining applications of genetic fingerprinting, include specific scenarios such as forensic cases or paternity tests.
Providing concrete examples demonstrates understanding and helps to illustrate your points effectively.
Interpret DNA fingerprint evidence carefully
