How can cells in a multicellular organism differentiate?

• They express some of their genes but not others.

• They all have a different genetic composition.

• Different cells contain a different set of chromosomes.

• Different cells do not have some of the genes.

What is the sequence of stages during the cell cycle?

• G1 → S → G2 → mitosis → cytokinesis

• mitosis → G1 → G2 → cytokinesis → S

• G1 → G2 → S → mitosis → cytokinesis

• G1 → G2 → mitosis → cytokinesis → S
