Mitosis

Question 1

What are the names of all the phases on mitosis

Answer 1

Prophase, metaphase, anaphase, telophase then cytokinesis

Question 2

What happens during prophase in mitosis?

Answer 2

The two pairs of homologous chromosomes condense getting shorter and fatter and centrioles start moving to opposite poles. The nuclear envelope starts to break down

Question 3

What happens during metaphase in mitosis?

Answer 3

Spindle fibres (protein) form from the centrioles and attach to the centromeres of the chromosome to align them in the middle.

Question 4

What occurs during the anaphase of mitosis?

Answer 4

The spindle fibres contract pulling apart the chromosomes from the centromeres pulling to each pole one of each sister chromatid.

Question 5

What occurs during telophase of mitosis?

Answer 5

Chromatids uncoil and stretch to become long and thin and a new nuclear envelopes forms around the two separated chromosome. The cytoplasm divides by cytokinesis to form two genetically identical daughter cells to the original cell

Question 6

What occurs during interphase?

Answer 6

DNA is unraveled and replicates, normal functions carries out but every organelle is doubled and the amount of ATP increases
