Cell Growth & Division Test Review II

Cells that are not dividing remain in the

• mitosis phase.

• S phase.

• G0 phase.

• G2 phase.

Proteins that bind to cells and stimulate cell division are called

• enzymes.

• kinases.

• growth factors.

• carcinogens.

These structures are found at the end of a chromosome and protect DNA from being damaged during cell division.

• histones

• centromeres

• telomers

• centrosomes

The synthesis (S) phase is characterized by

• DNA replication.

• cell division.

• replication of mitochondria and other organelles.

• the division of cytoplasm.

Which type of stem cell can grow into any other cell type?

• somatic

• multipotent

• totipotent

• pluripotent

The region of a chromosome where two sister chromatids are held together is called a

• spindle.

• centromere.

• nucleosome.

• centriole.
