Chapter 1.3 Producing new cells

Question 1

The nucleus of a cell contains genetic information (DNA) organised into

Answer 1

chromosomes

Question 2

The chromosome complement of a cell is the

Answer 2

number and type of chromosomes it contains

Question 3

The chromosome complement of most cells is

Answer 3

diploid

Question 4

A diploid is

Answer 4

a cell containing two sets of chromosomes

Question 5

The nucleus controls the production of new cells called

Answer 5

mitosis

Question 6

Replication is the process by which DNA

Answer 6

copies itself

Question 7

During mitosis each

Answer 7

chromosome is replicated

Question 8

A a replicated chromosome is called a

Answer 8

chromatid

Question 9

In mitosis the nucleus of a diploid parent cell

Answer 9

divides to produce two diploid nuclei

Question 10

Daughter cells are genetically

Answer 10

identical to their parent cell

Question 11

The first step of mitosis is:

Answer 11

the chromosomes replicating and becoming visible as pairs of chromatids.

Question 12

The second step of mitosis is:

Answer 12

The chromosomes line up at the equator and their chromatids are pulled to opposite poles by spindle fibers to form two new nuclei.

Question 13

After mitosis, the cell cytoplasm

Answer 13

splits between the nuew nuclei to from two daughter cells.

Question 14

Cells can be induced to undergo mitosis and cell division artificially in

Answer 14

cell culture

Question 15

Cell culture requires aseptic techniques so that

Answer 15

the growth of other cells such as bacteria is prevented and the culture remains uncontaminated.

Question 16

Cell culture requires nutrient agars or broths so the cells

Answer 16

can grow and divide.

Question 17

In cell culture factors such as

Answer 17

temperature, pH and oxygen levels are controlled.
