Mitosis

Question 1

How long does the interphase last

Answer 1

12-14 hours

Question 2

What occurs during the interphase

Answer 2

Gap phase 1, DNA Synthesis Phase and Gap phase 2 (the stage in the cell cycle where the cell is not dividing)

Question 3

What occurs during gap phase 1

Answer 3

Cell increases in size, produces RNA and proteins. Cell organelles replicate.

Question 4

What occurs during Synthesis Phase

Answer 4

DNA replication - chromatids formed

Question 5

What occurs during gap phase 2

Answer 5

checking for mutations to make sure cell is ready for mitosis. continues to grow and make proteins too, including microtubules for mitosis

Question 6

What is cytokinesis

Answer 6

Division of the cytoplasm

Question 7

what is mitosis

Answer 7

Process of nuclear division before the cell physically divides

Question 8

What is the order of mitosis

Answer 8

Prophase, metaphase, Anaphase, Telophase (PMAT)

Question 9

How long is the Prophase

Answer 9

1 to several hours

Question 10

What occurs during the prophase

Answer 10

Chromatin shortens and thickens, each chromosome appears as 2 chromatids held by a centromere, 2 sets of centrioles move to opposite poles.

Question 11

How long is the metaphase

Answer 11

5 to 15 minutes

Question 12

What occurs during metaphase

Answer 12

centromeres attach to spindle fibres, so chromatids line up on the equatorial plane.

Question 13

How long is anaphase

Answer 13

Shortest stage - a few minutes

Question 14

What occurs during anaphase

Answer 14

microtubules shorten, therefore spindle fibres shorten, dragging chromatids apart (now just singular chromosomes again) and chromosomes are pulled to opposite ends of the cell

Question 15

How long is Telophase

Answer 15

10 - 30 mins

Question 16

What occurs during telophase

Answer 16

New nuclear membranes begin to enclose around chromosomes, new nucleoli, chromosomes decondense and disappear, spindle starts to disappear.
