Cell Cycle
More Cell Cycle
Even MORE Cell Cycle
Whaaaat?? More cell cycle??
Again with the cell cycle!
100
What is the phase in which a cell spends most of its time?
Interphase
100
When do cells copy their DNA?
The S stage of interphase.
100

What do the chromosomes do during metaphase?

Line up in the center of the cell on the metaphase plate

100
When during mitosis does the cell lengthen?
During anaphase
100
During what does the cytoplasm and its contents divide into two identical daughter cells?
During cytokinesis
200

What is considered the growth phase of interphase?

G1

200
What holds identical pairs of chromosomes together during the S stage?
Centromere
200

Which phases of mitosis are exact opposites of each other 

Prophase and telophase 

200
When do the spindle fibers break down?
During telophase
200

What is one reason that cells go through the process of mitosis?

To replace old cells, for growth or for repair 

300

During the mitotic phase, what is the order of the phases

Prophase, metaphase, anaphase, and telophase

A student is examining a single onion root tip cell under a microscope. Based on their observations, the student proposes that the onion root tip cell has completed interphase and is now in the first phase of mitosis (prophase). What evidence would best support the students’ claim?

There are chromosomes, not threadlike chromatin, in the cell and the nuclear envelope broke down

300

When do spindle fibers appear?

Late Prophase/Early Metaphase

300
During what phase does the copied DNA condense into chromosomes?
During prophase
300

Uncontrolled cell growth can also be called

Cancer

400

Some cells stop the cell cycle in what stage of interphase?

G1 or G2

400

What are the two stages of the cell cycle besides interphase?

Mitosis and cytokinesis

400
When do the sister chromatids separate?
During anaphase
400
When are two new identical nuclei form?
During telophase
400
How many PAIRS of chromosomes do humans have?

23

500

What best describes the result of DNA replication during S phase?

Two identical DNA molecules are produced. Each one has a strand that is old DNA and one that is new DNA.

500

What disappears during prophase? 

The nuclear envelope/membrane

500

Most of the cells in your body are made through which process?

Mitosis

500

What are the three main parts of the entire cell cycle?

Interphase, M phase (Mitosis), Cytokinesis

500

What is the first thing that happens when a new cell is produced?

It grows or gets larger as it enters G1
