Cell Cycle & Mitosis - exam practice

Which statement about the behaviour of chromosomes during mitosis is correct?

The statements describe events during the mitotic cell cycle:

1 - chromosomes migrate to opposite poles of the cell

2 - chromosomes arrange themselves at the equator of the cell

3 - chromosomes condense and the nuclear membrane disappears

4 - centromeres divide

What is the correct order of three of these events in the mitotic cell cycle?

The diagram below shows a cell during cell division. The diploid number of this cell is three.

In which phase of cell division is the cell in the diagram above?

What occurs in anaphase of mitosis?

Which is always true of cytokinesis?

1 - cell organelles replicate

2 - cell organelles are divided between two cells

3 - nuclear envelope reforms

Which process occurs during prophase of the mitotic cell cycle in an animal cell?

What occurs during metaphase of mitosis?

Some chemicals, used to stop tumour growth, work by preventing the DNA double helix from uncoiling and separating.

During which stage of the cell cycle would they act?

Which processes occur by mitosis?

1 - cloning of plasma cells

2 - gamete production

3 - replacing damaged cells

Bacterial cells divide by a process called binary fission.

Which macromolecules must be synthesised for binary fission?

1 - cell membrane proteins and RNA

2 - DNA and peptidoglycan

3 - enzymes and cellulose
