Mutations (Part 1)

It is important to understand mutations because of the important role they are supposed to play in the theory of evolution. This introductory video defines mutations as mistakes made during cell division (both mitosis and meiosis), defines three kinds of mutations, lists some causes of mutations, and briefly describes some effects of mutations on living organisms.

Mutations (Part 2)

This video further expands the concepts introduced in Mutations (Part 1). It explains two kinds of mutations that affect a single gene (point mutations and frameshift mutations) and describes four kinds of mutations that can affect entire chromosomes (gene duplication, gene deletion, gene inversion, and translocation).
