Cell Division Notes

Front 1

Between cell divisions, DNA is long and stringy and exists as􏰀

Back 1

Chromatin

Front 2

DNA makes a blank of itself before cell division.

Back 2

copy

Front 3

In eukaryotes, the DNA wraps around proteins to make a compact

structure called a

Back 3

chromosome

Front 4

The two copies of DNA make up the two identical halves of

chromosomes. Each half is called a

Back 4

sister chromatid

Front 5

The two chromatids are attached at a􏰀point called a

Back 5

centromere

Front 6

When the cell divides, each of the two new cells will receive one

chromatid from each

Back 6

chromosomes

Front 7

Humans have blank pairs of chromosomes for a total of blank.

Blank is the process by which cells reproduce.

Cell Division

Front 10

Blank is the process of cell division in prokaryotes.

Back 10

Binary Fission

Front 11

Blank is the process of cell division in eukaryotes.

Back 11

Mitosis

Front 12

Mitosis results in 2 new cells with genetic material that is blank to the genetic material of the original cell

Back 12

Identical

Front 13

Mitosis occurs in organisms undergoing...

Back 13

Growth, Development, Repair, and Asexual reproduction.

Front 14

Blank reproduction is the production of offspring from one parent.

Back 14

Asexual

Front 15

One example of asexual reproduction is blank seen in bacteria.

Back 15

Binary fission

Front 16

The blankis the repeating set of events in the life of a cell. 17.The time between cell division is called blank.

Back 16

Cell Cycle

Interphase

Front 17

The time between cell division is called

Back 17

interphase

Front 18

Blank consists of three phases:

a). blank of the cell

b.) blank of the DNA (synthesis)

Back 18

Interphase

a.)growth

b.)replication

Front 19

Mitosis is the division of the blank, which occurs during cell division.

Back 19

nucleus

Front 20

Mitosis is divided into stages:

Back 20

Prophase, Metaphase, Anaphase, and Telophase.

Front 21

Mitosis results in blank daughter cells that are genetically identical to the

original cell.

Front 22

Blank is the first phase of mitosis.

a) Chromatin condenses to form...

b.) The nucleolus and the nuclear membrane break down and...

c.)In animal cells, cylindrical bodies called centrioles appear which

produce

Back 22

Prophase

a.)chromosomes

b.) disappear

c.) spindle fibers

Front 23

Blank is the 2nd phase of mitosis.

a.)Spindle fibers attach to the blank of the chromosomes and

move them to the center of the dividing cell.

Back 23

Metaphase

a.) centromere

Front 24

The third step of mitosis is...

a.) The chromatids of each chromosome separate at the centromere

and slowly move toward the blank poles of the dividing cell.

Back 24

Anaphase

a.) opposite

Front 25

The fourth step of mitosis is...

a.) The spindle fibers disassemble

b) the chromosomes return to a less tightly coiled blank state.

c.) A blank envelope forms around each set of chromosomes, and a nucleolus forms in each of the newly forming cells.

Back 25

Telophase

a.)

b.) Chromatin

c.) nuclear

Front 26

During blank in animal cells, a blank pinches in and eventually separates the dividing cell into two cells.

Back 26

Cytokinesis

Contractile ring

Front 27

In plant cells, a blank separates the dividing cell into two cells.

Back 27

cell plate

Front 28

Cell division in eukaryotes is controlled by blank called cyclins.

Back 28

proteins

Front 29

Blank may result if cells do not respond to control mechanisms and continue to divide nonstop.

Back 29

Cancer

Front 30

When the same type of cells normally divide to make a group of cells that perform the same function, they form a blank.

Back 30

TISSUE

Front 31

A group of tissues that work together form an blank.

Back 31

ORGAN

Front 32

A group of organs that work together form an blank.

Back 32

ORGAN SYSTEM

Front 33

All of the organ systems together form an blank.
