TEST THAT IMA FAIL ): mitosis and what not

Question 1

What are the stages to mitosis (in order obvi)

Answer 1

Interphase (well not technically apart of mitosis), Prophase, Metaphase, Anaphase, Telophase, Cytokinesis

Question 2

What happens in interphase

Answer 2

G1 and S and G2

Question 3

What happens in interphase G1

Answer 3

The cells grow normally until they get a signal to divide and increase in size

Question 4

What happens in interphase S

Answer 4

The DNA/Chromosomes double

Question 5

How many chromosomes does a cell have before interphase

Answer 5

46

Question 6

How many chromosomes does a cell have after interphase

Answer 6

92

Question 7

How many chromosomes does a cell have after cytoplasm

Answer 7

46

Question 8

What happens in prophase

Answer 8

Nuclear membrane/envelope starts to disappear, chromosomes condense and spindle fibers form

Question 9

What is the Nuclear membrane/envelope

Answer 9

A layer that encloses the nucleus and is where all the chromosomes reside

Question 10

What are spindle fibers?

Answer 10

a network of threads that are formed during the cell division process

Question 11

What happens in metaphase

Answer 11

Spindle fibers move chromosomes to the center

Question 12

What is the center called during metaphase

Answer 12

metaphase plate or equator

Question 13

What happens in anaphase

Answer 13

Spindle fibers contract pulling the sister chromatids to opposite ends of the cell

Question 14

What are sister chromatids

Answer 14

One half of a chromosome

Question 15

What happens in telophase

Answer 15

The nuclear membrane starts to reform and spindle fibers starts to disappear and cleavage furrow forms in animal cells and cell plates in plant cells, and chromosomes becomes loose

Question 16

What happens in cytokinese

Answer 16

Cytoplasm completely splits and forms two identical daughter cells.

Question 17

What are somatic cells

Answer 17

They are any cell that isn’t a reproductive cell and all of them go through Mitosis

Question 18

What is crossing over in Meiosis

Answer 18

This happens during prophase 1 and is when pieces of homologus chromosomes exchange pieces to create new combinations, happens at the chiasma. this increase gentic diversity?
(AKA EXCHANGE ON GENITIC MATERIAL)

Question 19

What does Meiosis have that Mitosis doesn’t

Answer 19

They have 2 rounds of divison with the second phase not having interphase

Question 20

Start parent chromosome number and ending daughters (meiosis)

Answer 20

They start with 46 and after S stage has 92 and at the end of meisois 1 it as 46 and at the end of meisois 2 it has 23.

Question 21

How many cells are there at the end of meisosis.

Answer 21

4

Question 22

Are the cells at the end of Meiosis the same?

Answer 22

No they aren’t the same because they have differnt homologous

Question 23

What type of cells do mitosis make and Meiosis

Answer 23

Mitosis makes dipoloid cells meaning they are 2n meaning they have 2 copies of chromosomes and Meiosis makes haploid meaning they are N, only one copy of each chromosome

Question 24

Similarities between mitosis and meiosis

Answer 24

Both forms of cell divison, both go through interphase and dna replication before division

Question 25

Diff between mitosis and meiosis

Answer 25

Mit makes 2 Mei makes 4
Mit cells are identical Mei cells arent
Mei is in gammies mit is in somatic
Mei has crossing over

Question 26

What do nerve and muscle cells go through

Answer 26

Nothing! #ate#leftnocrumbs## these are g0

Question 27

what happens in G2

Answer 27

Organelles double and cell double checks to make sure that it is ready for divison
