8

What is the Genome?

The entirety of all DNA in a cell

9

True or False: All cells in an organism have the same DNA

True

10

How do cells differentiate?

This is a result of selective usage of information in DNA by specific cells

11

True or False: Present day cells evolved from the same ancestral cells

True

12

A change in DNA

Mutation

Cell Membrane

Encloses all internal components Controlls entry and exit of materials

23

In bacterial cells, where is the genetic material stored?

It is not enclosed in a membrane, but localized in a nucleoid
