GCSE Biology - What are DNA Mutations? #67

The video tutorial explains mutations as changes in DNA sequences, often occurring during cell division. Carcinogens and radiation can increase mutation risks. DNA's role in coding proteins is discussed, highlighting how mutations can alter protein function. Most mutations are harmless, affecting non-coding DNA. The tutorial covers substitution, insertion, and deletion mutations, detailing their effects on DNA sequences and protein synthesis.

What is the significance of non-coding DNA in relation to mutations?

Explain the difference between substitution mutations and insertion mutations.

How do deletion mutations affect the DNA sequence?
