Flashcards in Mitosis / Meiosis Deck (27):
1

discrete units of hereditary information consisting of double stranded DNA

genes

2

The process in which single celled organisms divide into two daughter nuclei

mitosis

3

What is the division of cytoplasm called?

cytokinesis

4

What are the three stages of interphase?

G1, S, G2

5

What happens in G1?

cytoplasmic mass increases, new organelles are formed, and some organelles divide in 2

6

What happens in the S phase?

chromosomes replicate

7

What happens in G2?

cells prepare for mitosis, Enzymes and other proteins are synthesized, centrioles divide and begin to move to opposite sides of the cell

8

What happens in the M phase?

the nucleus and cytoplasm divide

9

in which phase does the chromatin begin to coil and condense?

early Prophase

10

in which phase does the nuclear envelope break down and the nucleoli disappears?

early Prophase

11

In which phase does the chromatin form chromosomes?

Late Prophase

12

In which phase does the spindle fibers extend between the centrioles and move the chromosomes to the center?

Late Prophase

13

What happens to the spindle fibers and the chromosomes during late prophase?

the spindle fibers extend between the centrioles and the chromosomes move to center

14

where do double stranded chromosomes lie during metaphase?

the equator

15

What are the two sister chromatids held together by during metaphase?

the centromere

16

how does Metaphase end?

with the centromere splitting

17

What happens during anaphase?

The sister chromatids separate and are pulled to opposite poles by spindle fibers.

18

What is a chromatid called after anaphase?

a chromosome

19

how does anaphase end?

when the chromosomes reach the poles

20

what begins when anaphase ends?

telophase

21

what happens during telophase?

the spindle begins to break down, chromosomes uncoil, new nuclear envelope forms

22

This forms during cytokenises in animal cells at the equator and it pinches the parent cell cytoplasm in two

cleavage furrow

23

in which phase does the centromere split?

metaphase

24

in which phase do the sister chromatids separate?

anaphase

25

what is the mass of DNA and proteins in an uncoiled state called?

chromatin

26

where are centrioles located?

just outside the nucleus

27

What are the phases of Mitosis?

prophase, metaphase, anaphase, telophase, cytokenises
