Cell cycle and DNA

Question 1

What happens in G1 stage of cell cycle

Answer 1

Growing and doing function

Question 2

What happens in S phase of cell cycle

Answer 2

DNA synthesis and replication

Question 3

What happens in G2 phase of Cell Cycle

Answer 3

Preparing for cell division

Question 4

What happens in The Mitosis stage of cell division

Answer 4

Nuclear division Chromosomes split PMAT are the 4 stages Prophase Metaphase Anaphase Telophase

Question 5

What happens in the Cytokinesis stage of the cell cycle

Answer 5

Cytoplasm division

Question 6

How did G1 and G2 get there name

Answer 6

Because scientist didn’t have strong enough microscopes so they named the spaces in between Gap 1&2

Question 7

What are the two critical checkpoint stages

Answer 7

G1 G2

Question 8

Where does DNA synthesis happen in eukaryotic cells

Answer 8

S phase

Question 9

What two processes make up the M stage

Answer 9

Mitosis and Cytokenesis

Question 10

Among different cells which stage varies the most

Answer 10

G1

Question 11

Why does a skin cell divide fast than a liver cell

Answer 11

Skin cells have more wear and tear so need replacement more

Question 12

What is G0

Answer 12

Invetween G1 And S phase Cell does it’s function

Question 13

Which increases faster as the cell grows surface area or volume

Answer 13

Volume

Question 14

What must be coordinated for cells to stay the same size generation to generation

Answer 14

Growth and division

Question 15

What process divides the cells cytoplasm

Answer 15

Cytokinesis

Question 16

What process divides the cell nucleus and it’s contents

Answer 16

Mitosis

Question 17

A chromosome is one long continuous thread of what

Answer 17

DNA

Question 18

Why do chromosomes condense at the starts of mitosis

Answer 18

So they can be divided easier

Question 19

Why are chromosomes not condensed during all stages of the cell cycle

Answer 19

So genes can be accessed

Question 20

How does interphase prepare the cell to divide

Answer 20

Duplicates DNA and organelles

Question 21

Why can’t plant cells membrane pinch together What does it do instead

Answer 21

Because the cell wall A cell plate is laid down between the two nuclei

Question 22

DNA wraps around organizing proteins called what

Answer 22

Histones

Question 23

What is the loose combination of DNA and proteins

Answer 23

Chromatic

Question 24

Sister chromatids meet where

Answer 24

Centromere

Question 25

The ends of DNA molecules form structures to prevent the loss of genes what are they called

Answer 25

Telomere

Question 26

What is Chromatin

Answer 26

Mass of genetic material composed of DNA and proteins

Question 27

What is a chromatid

Answer 27

One half of two identical copies

Question 28

What is prophase

Answer 28

Chromatin condensed into double rod shape Nuclear membrane disappears

Question 29

What is metaphase

Answer 29

Chromosomes align at the cell equator before being separated

Question 30

What is anaphase

Answer 30

Replicated chromosomes are split and moved to opposite poles

Question 31

What is Telophase

Answer 31

Nuclear membrane comes back final stage
