Mitosis Flashcards

1
Q

Define mitosis

A

Type of nuclear division that maintains the chromosomes number; each new daughter cell contains the same genetic information as the parent cell. They are also genetically identical to each other.

Q

Events during prophase

A

Chromosomes condense.

Centrioles split and move to opposite sides of the cell, forming spindle.

Nuclear envelope breaks down

Q

Events during metaphase

A

Nuclear envelope gone.

Spindle fibres attach to the centromeres of each chromosome.

Chromosomes line up at the equator.

Q

Events in anaphase

A

The chromosomes break apart at the centromere.

Motor proteins pull each sister chromatid of each pair towards opposite poles.

Q

Events in telophase

A

Separated chromosomes reach the poles.

A new nuclear envelope forms around each set of chromosomes.

Cel now contains two nuclei each genetically identical to each other and to the parent cell.

Q

Events of cytokinesis

A

Cell will completely divide into two daughter cells (cytoplasm + cell membrane separates).

Each daughter cell will be identical to each other and their parent cell.

Division different for plants/animals
