Mitosis And The Cell Cycle

Question 1

What is the series of stages through which cells divide called?

Answer 1

Cell cycle

Question 2

What happens during the cell cycle, in terms of genetic material?

Answer 2

The genetic material is doubled and then split into two identical cells

Question 3

Before a cell can grow, what does it need to do?

Answer 3

Grow and increase the number of sub-cellular structures such as ribosomes and mitochondria

Question 4

The DNA ___________ to form two copies of each ____________

Answer 4

Replicates

Chromosome

Question 5

In ________ one set of chromosomes is pulled to each end of the cell and the nucleus ________

Answer 5

Mitosis

Divides

Question 6

The ___________ and cell __________ divide to form two identical ______

Answer 6

Cytoplasm
Membranes
Cells

Question 7

What is cell division in mitosis important in?

Answer 7

The growth and development of multicellular organisms

Question 8

What are the three stages of the cell cycle?

Answer 8

DNA replication
Mitosis
Meiosis

Question 9

What happens in DNA replication?

Answer 9

The DNA ‘unzips’ to form single strands

New double strands form by complementary base pairing.

Question 10

What happens during mitosis?

Answer 10

During mitosis, the chromosomes:

Line up along the centre of the cell

Divide

Copies then move to opposite poles (ends) of the cell

Question 11

What happens during meiosis?

Answer 11

In meiosis, the chromosome number is halved and each cell is genetically different.
