... The environment of a cell has changed. Let’s say that there is suddenly lactose sugar present! The cell must make loads of lactase right away. Name some ways that the cell can gear up production of lactase quickly. To illustrate the impact that mutations can have on a living thing, some made-up numb ...
Lecture 16 - DNA, RNA, and Heredity
