Pre-course 2: Cell Division

Which cell can enter G0 phase? Mark all the correct answers.

• Cell is partially differentiated

• Differentiated cell which is not dividing

• Cell with detected error

• Cell which is getting ready for division

• Cell right after division phase

In which organelle the main processes of S phase take place?

• Golgi apparatus

• Endoplasmic reticulum

• Mitochondrion

• Nucleus

• Lysosomes

Put the events in the following order: prophase-prometaphase-metaphase-anaphase-telophase

Nucleolus is not visible anymore. Centrioles move to the cell poles. Fragmentation of nuclear envelope take place. Which cell division phase is described?

• Prophase

• Prometaphase

• Metaphase

• Anaphase

• Telophase

Chromosomes are highly condensed and located in the equatorial plane. Which phase is described?

• Prophase

• Prometaphase

• Metaphase

• Anaphase

• Telophase

Disintegration of mitotic spindle. Nuclear envelope is reformed. Which phase is described?

• Prophase

• Prometaphase

• Metaphase

• Anaphase

• Telophase

By shortening and movement of mitotic spindle chromosomes move toward the cell poles. Which phase is described?

• Prophase

• Prometaphase

• Metaphase

• Anaphase

• Telophase

Interkinesis is a period between meiosis I and meiosis II.

• Yes

• No

Does DNA replication take place during the interkinesis?

• Yes

• No

If the DNA content of a diploid cell in the G1 phase of the cell cycle is x, then the DNA content of a single cell at metaphase of meiosis II would be:

• 0.25 x

• 0.5 x

• x

• 2 x
