Cell Division

Question 1

Cell Continuity

Answer 1

Cell continuity means that all cells develop from pre-existing cells

Question 2

Chromosomes

Answer 2

Chromosomes are coiled threads of DNA (which forms genes) and protein that become visible in the nucleus at cell division

Question 3

Gene

Answer 3

A gene is a section of DNA that contains the instructions for the formation of a protein

Question 4

Haploid Cells

Answer 4

A haploid cell has one set of chromosomes, i.e. it has only one of each type of chromosome in the nuclues

Question 5

Diploid Cells

Answer 5

A diploid cell has two sets of chromosomes, i.e. it has two of each type of chromosome in the nucleus

Question 6

Homologous Pair

Answer 6

A homologous pair is two chromosomes of similar size with the same sequence of genes

Question 7

Cell Cycle

Answer 7

The cell cycle is the changes that take place in a cell during the period between one cell division and the next

Question 8

Interphase

Answer 8

Interphase is the phases in the cell cycle when the cell is not dividing

Question 9

Mitosis

Answer 9

Mitosis is a form of nucleus division in which one nucleus divides to form two nuclei, each containing the same number of chromosomes with identical genes

Question 10

Cancer

Answer 10

Cancer is a group of disorders in which certain cells lose their ability to control both the rate of mitosis and the number of times mitosis takes place`

Question 11

Meiosis

Answer 11

Meiosis is a form of nuclear division in which the four daughter nuclei contain half the chromosome number of the parent nucleus

Question 12

Centromere

Answer 12

The centromere is the point at which the chromosomes are attached in a double-stranded chromosome
