mitosis

Question 1

Define what mitosis is

Answer 1

Single cell division which produces 2 genetically identical daughter cells

Question 2

list the phases in IPMAT

Answer 2

interphase, prophase, metaphase, anaphase, telophase

Question 3

is cytokinesis in mitosis?

Answer 3

no

Question 4

describe what happens in interphase

Answer 4

During the first stage, the cell prepares for cell division by replication, to produce two copies of each chromosome

Question 5

describe what happens in prophase

Answer 5

This is the longest stage, as the duplicated chromosomes condense and centrioles start to move at each end of the cell. (creates mitotic spindle)

Question 6

describe what happens in metaphase

Answer 6

Chromosomes now line up along the centre of the cell

Question 7

describe what happens anaphase

Answer 7

Sister chromatids are drawn to opposite poles of the dividing cells by mitotic spindles

Question 8

describe what happens in telophase

Answer 8

Nucleus membrane starts to reform around separates sister chromatids

Question 9

As pro - metaphase is not necessarily stated in mitosis, describe what happens in that stage.

Answer 9

nucleus breaks down and spindles attach to sister chromatids

Question 10

Relatively, what are the roles of mitosis in terms of keeping an individual healthy?

Answer 10

Promote growth in multicellular organism in which growth relies of mitotic division eg, morula to blastocyst
Repairs damaged tissues
Replaces worn out tissues
