C6 cell division

Question 1

What is the cell cycle split into?

Answer 1

Mitosis and interphase

Question 2

What is G1 in the cell cycle ?

Answer 2

Where cycle growth occurs
The organelles are doubling

Question 3

What is S in the cell cycle stand for?

Answer 3

Synthesis

Question 4

What happens in S1?

Answer 4

DNA synthesis / replication , transcription and translation
Very Short time
We don’t want the DNA to be open for too long because of mutation

Question 5

What is G2?

Answer 5

It’s is for cell growth but in this case it replicates proteins for mitosis
Proteins contains tubeles
Proteins only have to be specific for mitosis in this case centromeres

Question 6

What is the Final phase of the cell cycle ?

Answer 6

Mitosis

Question 7

What is G0?

Answer 7

The phase of the cell cycle during which a cell is neither dividing nor preparing to divide

Question 8

What is mitosis and what is the function?

Answer 8

Mitosis is the identical cell division and the function is growth and repair and asexual reproduction

Question 9

What is the acronym to remember mitosis stages ?

Answer 9

PMAT

Question 10

What happens in the prophase ?

Answer 10

The DNA is enclosed in the nucleus
That Nucleus is disintegrated and now the DNA is free to move

Question 11

What happens in Metaphase in mitosis?

Answer 11

The chromosome move to the middle and lines up in the middle

Question 12

What happens in anaphase ?

Question 13

What happens in telophase?

Answer 13

In telophase , is opposite of prophase , the nuclear membrane of the nucleus starts to form before the cell splits

Question 14

What are tubeles ?

Answer 14

Tubules are a type of organelles which helps movement in and out of the cell and in cell division , it contain spindle fibres which help with the movement

Question 15

What phase are tubeles found?

Answer 15

Metaphase , either side of the cell

Question 16

What is a centromere?

Answer 16

Keeps two chromosome together in the middle , making a pair of chromosome

Question 17

What is meiosis and what is the function?

Answer 17

It divides twice
The stages are numbered
Sexual

Question 18

What are the stages of meiosis ?

Answer 18

Interphase - cell growth, DNA replications , protein gets ready for meiosis

Prophase 1 - nuclear membrane starts to dissociate

Metaphase 1 - reason why siblings look different , because we don’t know which side the blue or pink will be , key thing that happens is that we don’t know which order will be mum or dad

Anaphase 1- due to this , when they get pulled apart , they will be a random combination hence there will be diversity

Telophase - two nuclear membrane form

Cytokinesis

Prophase 2

Question 19

How many pairs are there after interphases

Answer 19

46 pairs , 23 dad and 23 mum , then they replicate

Question 20

What is chiasmata?

Answer 20

The point at which the dad and mum genes cross over
At the point where homologous chromosomes cross over
