Mitosis

Question 1

what are centromeres?

Answer 1

where the sister chromatids are attached.

Question 2

what are chromosomes?

Answer 2

structures that contain genetic materials passed down from generations.

Question 3

what are sister chromatids?

Answer 3

two structures that have identical DNA.

Question 4

what are the four phases of mitosis?

Answer 4

Prophase
Metaphase
Anaphase
Telophase

Question 5

what is a chromatin?

Answer 5

the relaxed form of DNA in the cell’s nucleus.

Question 6

what is a spindle apparatus?

Answer 6

a structure that helps move and organizes chromosomes before cell division.
made of spindle, centrioles, and aster fibers

Question 7

what is anaphase?

Answer 7

the third phase of mitosis.

the sister chromatids are pulled apart and to opposite ends of the cell.

Question 8

what is cylins?

Answer 8

proteins that bind to enzymes.

Question 9

what is cytokinesis?

Answer 9

the third stage of the cell cycle

where the cytoplasm divides and creates a new cell.

Question 10

what is interphase?

Answer 10

the first stage of the cell cycle where the cell grows and replicates DNA.

Question 11

what is metaphase?

Answer 11

the second stage of mitosis.

where the sister chromatids are pulled by motor proteins along the spindle apparatus.

Question 12

what is metaphase?

Answer 12

the second stage of the cell cycle.

DNA is divided into two sister chromatids.

Question 13

what is prophase?

Answer 13

the first stage of mitosis.

the chromatin condenses into chromosomes and the nucleus disappears.

Question 14

what is telophase?

Answer 14

the last phase of mitosis.

the chromatids arrive at the cell’s poles and began to decondense.

Question 15

what is the cell cycle?

Answer 15

a cycle of cells reproducing and dividing.

Question 16

what are stem cells?

Answer 16

Unspecialized cells that can turn into specialized cells under the right conditions.

Question 17

what is Apoptosis?

Answer 17

a programmed cell death

Question 18

If a cell with 36 chromosomes undergoes mitosis, how many chromosomes will each of the two new cells have?

Answer 18

36

Question 19

Why does the DNA need to condense before starting Mitosis?

Answer 19

to reduce mistakes and make it more organized.

Question 20

What does mitosis produce?

Answer 20

nucleus

Question 21

How many chromosomes are in one cell of a human?

Answer 21

46

Question 22

In cell division, which cell part divides first?

Answer 22

Nucleus

Question 23

Which part of the cell is divided during Mitosis?

Answer 23

Nucleus

Question 24

DNA replication occurs during ___________.

Answer 24

interphase

Question 25

Mitosis, a stage in the cell cycle, is important for what reason? division of the cytoplasm growth and repair of an organism reduction of the cell’s chromosome number removal of diseased cells

Answer 25

growth and repair of an organism

Question 26

Which description best fits the activity of a cell during interphase?

Answer 26

The cell carries on metabolism.

Question 27

A cell that undergoes repeated mitosis without cytokinesis would have _______.

Answer 27

many nuclei.
