What is the result when a single cell reproduces by mitosis?

• two cells with genetic material identical to the parent cell

• two cells with half the genetic material of the parent cell

• four cells with half the genetic material of the parent cell

• four cells with genetic material identical to the parent cell

What does replication of DNA during interphase ensure during cell replication?

• crossing over occurs prior to cell division

• mutations are corrected before the cell divides

• genetic variation is created in daughter cells

• each daughter cell gets an exact copy of the cell's DNA

Why is interphase the longest stage of the cell cycle?

• the nucleus takes numerous days to divide

• gametes are produced over a long period of time

• the cytoplasm and cell membrane separate after telophase

• the cell grows, metabolizes, and synthesizes more genetic material

What is the correct order for mitosis?

• telophase, metaphase, prophase, anaphase

• anaphase, metaphase, prophase, telophase

• prophase, metaphase, anaphase, telophase

• telophase, anaphase, metaphase, prophase
