Unit 6 - Mitosis/Meiosis Study Guide Flashcards
There are two parts of the cell life cycle, mitosis and interphase.
False - Interphase, Mitosis, Cytokinesis
During meiosis I, homologous chromosome pairs are separated when the centromeres split apart.

Crossing over would most likely occur during which stage of the cell cycle?
when homologous chromosomes line up in pairs
What is the role of the spindle fibers?
They move chromosomes in the cell

False
By the end of prophase, each of the following has occurred except ____.
Lining up of chromosomes in the cell
Which of the cells depicted in the line graph in the diagram are most likely cancerous?
