What is a genome?
What phase are the events centerosomes are at opposite polls, chromosomes line up at the metaphase plate, and the microtubules are attached to each kinetochore
What is metaphase?
The most import checkpoint that checks for cell size, growth factors, and DNA damage
What is G1?
The cell cycle consists of
What is alternating phases of interphase and mitosis?
After DNA replication, chromatin condenses to form
What is a chromosome?
The two types of cells
What are somatic cells and gametes?
What are the two key events of anaphase
What are the separation of the sister chromatids to opposite sides and the elongation of the cell?
What event occurs after G1 when it signals stop? (be specific)
What is it enters G0 where some cells will stay forever or the cells get called back to the cycle?
Interphase consists of
What is G1, S, and G2?
The region on each sister chromatid where they are most closely attached
What is the centromere?
Homologous chromosomes are two chromosomes that have what three things in common
What is the same length, the same centromere position, and carry genes controlling the same characteristics?
Three key events of prophase (answers vary)
What are chromatin condenses, nucleoli disappear, duplicated chromosomes appear as sister chromatids, mitotic spindle begins to form, and centrosomes move away from each other?
Regulation of the cell cycle involves an internal control system that consists of (2 things)

What is singular,circular and linear chromosomes?
The difference of cytokinesis for plants and animal
What is in plants the vesicles travel to the middle of the cell to form a cell plate and for the animal a cleavage furrow appears due to a contractile ring of actin filaments?
Cell surface receptors recognize contact with other cells so this occurs
