the whole entire chromosome found in the nucleus
What is a genetic mutation
the making of a zombie
any change in the DNA base pairs
the process of duplicating the DNA in a cell
A substitution mutation occurs when

What types of living organisms have NO genetic material at all?
Insects
Bacteria
Plants
All living organisms have genetic material
Why do most changes to DNA have NO effect at all?
Because they're too minor to have any effect
Because the changes are offset by RNA, which cannot change
Because the changes are quickly repaired
Because the changes only occur in a few cells
In the video, Tim says that genetic mutations are permanent changes to DNA or RNA. What does this mean?
The changes are minor
The changes can't be undone.
The changes are major.
The changes can be undone.

What usually happens to a cell whose DNA has been damaged?
It has trouble manufacturing certain proteins
Its genetic material leaves the nucleus
It is able to produce twice as many proteins as a normal cell
It shrinks to half its normal size
How are cancerous cells different from normal cells?
Cancerous cells are shaped differently than normal cells
Cancerous cells divide more frequently than normal cells
Cancerous cells contain chemicals not found in normal cells
Cancerous cells need more oxygen than normal cells
Which of the following is an example of a beneficial mutation?
When an organism's lifespan becomes shorter.
When an organism becomes unable to reproduce.
When an organism's body becomes deformed.
When an organism develops immunity to a disease.
When a beneficial (adaptive) mutation spreads through an entire population of organisms, that population:
Becomes less common
Becomes more common
Goes extinct
Keeps mutating
