Put the following actions in order: DNA replicates, cell grows, cell divides, cell prepares for mitosis. 

• DNA replicates, cell grows, cell prepares for mitosis, cell divides
• cell grows, cell prepares for mitosis, DNA replicates, cell divides
• cell grows, DNA replicates, cell prepares for mitosis, cell divides
• DNA replicates, cell prepares for mitosis, cell grows, cell divides

which best describes the G2 phase

• the spindles form, the chromatin condenses into chromosomes, centrioles assist with spindles as well as the nuclear envelope breaks down.

• double checks the duplicated chromosomes for any errors as well as more cell growth, production of protein and organelles and prepares for mitosis.

• the cytoplasm of each cell is divided into two new cells.

The structure labeled A is a(n)

• chromatid
• centriole
• centromere
• chromophere

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

• In order for genetic information to be transferred into daughter cells.
• In order for the cell to be able to increase in size.
• In order for the DNA to be contained in the nucleus.
• In order for the cell to re-order the DNA sequencing in the new cells.

During meiosis I, what happens? 

• Sister chromatids are split
• Homologous chromosomes are split
• Four cells are created
• None of the other choices are correct

During interphase, a cell grows, duplicates organelles, and

• copies DNA
• divides the nucleus
• divides the cytoplasm
• produces a new cell

In prometaphase the spindle microtubules attach to the...
