Mitosis

Question 0

Interphase

Answer 0

Cell carries out normal functions

• cells DNA unravelled and replicated
• organelles are also replicated
• resulting in its ATP content increasing

Question 1

What’s cell cycle

Answer 1

Describes the events that take place as one parent cell divides to produce two new daughter cells which the each grow to full size.

Question 2

Prophase

Answer 2

• chromosomes condense, making them shorter and fatter
• proteins called centrioles start to move to the opposite poles of the cell.
• the nuclear envelope breaks and chromosomes are free to lie in the cytoplasm.

Question 3

metaphase

Answer 3

• chromosomes(each with two chromatids) line up along the middle of Cell, and are attached to spindle fibre by there centromere.

Question 4

Anaphase

Answer 4

• The centromeres divide separating each pair of sister chromatids.
• spindles contract pulling them towards opposite poles of cell, centromeres first.

Question 5

Telophase

Answer 5

• They uncoil and become long and thin.
• now that there chromosomes, a nuclear envelop forms around each group. Two new nuclei form.
• the cytoplasm divides and two new cells form. Identical to the parent cell.

Question 6

What method is used in observing the stages of mitosis?

Answer 6

Staining is used to have a clear view of the different stages of mitosis.
