By Mandy Fulton

Multiple Select

The main stages of Mitosis are (Choose all that Apply):

• Gap 1 (G1):   cell growth and normal functions

• DNA synthesis (S): copies DNA

• Gap 2 (G2): additional growth

• Mitosis (M): includes  division of the cell nucleus (mitosis) and division of the cell cytoplasm (cytokinesis)

Multiple Select

Mitosis occurs only if (choose two):

• It is a nerve cell

• the cell is large enough

• The surface area to volume ratio is small enough

• DNA undamaged

Multiple Choice

The rate of cell division:

• Is the same with the need of those types of cells

• Varies depending on the organism

• Is is highest for nerve cells

• Is higher for skin cells than for liver cells.

Multiple Choice

Surface area must:

• Be large enough to allow for adequate exchange of materials

• Must be small enough for genetic material to be conserved

• Must be unique

• Must be separate from cell growth.

Multiple Choice

Histones are:

• Supercoiled DNA

• Chromatin

• Spool-like proteins

• DNA double helix

Multiple Choice

A chromatid is:

• Held together by a telomere

• Centromeres protecting DNA

• Two sister chromosomes

• Half of a duplicated chromosome
