What phase does the synthsis of new DNA occur?

Back 8

S phase (synthsis)

Front 9

Back 9

Interphase

Front 10

What happens in the G1 phase?

Back 10

The dna double helix unwinds and expose the bases.
Transcribing

Front 11

How does the DNA double helix release to allow replication?

Back 11

Enzymes initate the process of unwinding the DNA and releasing 2 complementary strands of that DNA so DNA POLYMERASE can duplicate them.

Back 12

The number of deaths per 1,000 people per year.
" " births per year.

Front 13

What phase of interphase includes protein synthesis and cell growth?

Back 13

G1

Front 14

What are gamets?

Back 14

Cells that are formed via sexual reproduction.

Front 15

What is the process called which gametes reduce their DNA content

Back 15

meiosis

Front 16

Mitoosis can occur in cells such as? (3)

Back 16

Skin
Liver
Other organs in the digestive system

Front 17

What are celled called that have 2 sets of chromosomes called?

Back 17

Diploid

Front 18

Cells that contain a single set of chromosomes are called?

Back 18

Haploid

Front 19

What type of cells are fertilized eggs? haploid or diploid

Back 19

Diploid

Front 20

In a diploid cell, each individual chromosome has a twin chromosome called____.

Back 20

homologous

Front 21

In mitosis, the individual chromosome duplicated during what phase?

Back 21

S phase

Front 22

What is cytokinesis?

Back 22

Separtation of two sets of chromosomes into different cells. Then mitosis is complete.

Front 23

What phase is when:
The spindle fibers form and the centrioles moves to the opposite sides of the cell. The nuclear membrane disapears.

Back 23

Mitosis

Prophase

Front 24

What phase is when:
the chromosomes begin to separate from their daughters. Cytokineses begins.

Back 24

mitosis

Anaphase

Front 25

What phase is it when:
Identical sets of chromosomes are at the opposite ends of the cells. Spindle fibers disappear,nuclear membranes reappear, and cytokinesis completes.

Back 25

mitosis

Telophase

Front 26

What phase is it called when:
Homologous chromosomes condense and link in the process forming tetrad. This allows crossing over or recombination to occur.

Back 26

Meiosis
Prophase I

Front 27

What phase is it called when:
Homologous chromosomes separate, but the sister chromatids stay together.

Back 27

Meiosis
Anaphase I

Front 28

What phase is called when:
Cytokinesis has occurred and two haploid daughter cells are the result

Back 28

Meiosis
Telophase I

Mitosis and meiosis occur in all types of cells. T or F

Back 31

False: Mitosis occurs to replace old cells in all cell types, while meiosis occurs in gametes to bring about genetic variation amongst offspring.
