Answer 0

Mitosis is when a cell reproduces itself by splitting to form two identical offspring

Answer 1

For growth and repair

Question 2

Mitosis - In a cell that is not dividing what does the DNA do?

Answer 2

Spreads out in long strings

Question 3

Mitosis - if the cell get a signal to divide it duplicates it’s DNA. What does copied DNA form?

Answer 3

X-shaped chromosomes each arm is an exact duplicate of the other

Question 4

Mitosis - what do the Christine’s do before they split? (Step 3)

Answer 4

Chromosomes line up in the middle of the cell, fibres then pull them apart

Question 5

Mitosis - after the fibres pulled the chromosomes apart what happens?

Answer 5

The two arms of the Chromosome go to opposite ends of the cell

Question 6

Mitosis - what forms around the chromosomes after the chromosomes were just pulled apart

Answer 6

Membranes are formed around two neuclei (still joined together)

Question 7

Mitosis - the last stage is when the cytoplasm (membrane) around the neuclei divides, then what happens

Answer 7

You now hoe two new cells containing identically DNA

Question 8

Body cells usually have how many copies of chromosomes?

Answer 8

Two copies of each chromosome

Question 9
