Flashcards in Mitosis And The Cell Cycle Deck (11):
1

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

Cell cycle

2

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

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

3

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

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

4

The DNA ___________ to form two copies of each ____________

Replicates
Chromosome

5

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

Mitosis
Divides

6

The ___________ and cell __________ divide to form two identical ______

Cytoplasm
Membranes
Cells

7

What is cell division in mitosis important in?

The growth and development of multicellular organisms

8

What are the three stages of the cell cycle?

DNA replication
Mitosis
Meiosis

9

What happens in DNA replication?

The DNA 'unzips' to form single strands

New double strands form by complementary base pairing.

10

What happens during mitosis?

During mitosis, the chromosomes:

Line up along the centre of the cell

Divide

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

11

What happens during meiosis?

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