Q

What happens during Metaphase?

A

The chromosomes move towards the equator (middle) of the cell and spindle fibers link the chromatids of each chromosome to opposite poles

Q

DNA is called chromatin in this phase?

A

Interphase

17
Q

During what phase of the cell cycle is DNA replicated?

A

S

18
Q

What is the longest stage of the cell cycle?

A

Interphase

19
Q

In mitosis the two resulting cells are….

A

identical to the starting cell and identical to each other

20
Q

Why do human skin cells go through mitosis constantly?

A

To replace dead or damaged skin cells

21
Q

What does the starting cell become after it goes through mitosis (Cytokinesis inculded)?

A

It splits apart to create two new daughter cells

22
Q

What happens during G1 phase?

A

Cell growth

23
Q

What happens during S phase?

A

The cell replicates its DNA

24
Q

What happens during G2 phase

A

The cell grows again and prepares for mitosis

25
Q

During what phase is DNA called chromatin?

A

Interphase

26
Q

How many chromosomes do humans have?

A

46

27
Q

Where do the spindle connect onto chromosomes to pull them apart during metaphase?

A

Centromeres

28
Q

What happens during the G0 phase?

A

The cell rests instead of going through the cell cycle again

29
Q

What happens to DNA during S

A

It is duplicated
