Question 1

anaphase

Answer 1

stage of mitoses during which sister chromatids are separated from eachother

Question 2

binary fission

Answer 2

prokaryotic cell division process

Question 3

cell cycle checkpoint

Answer 3

mechanism that monitors the preparedness of a eukaryotic cell to advance through the various cell cycle stages

Question 4

cell cycle

Answer 4

ordered sequence of events that a cell passes through between one cell division and the next

Question 5

cell cycle (again)

Answer 5

ordered series of events involving cell growth and cell division that produces two new daughter cells

Question 6

cell plate

Answer 6

structure formed during plant cell cytokinesis by golgi vesicles, forming a temporary structure and fusing at the metaphase plate – ultimately leads to the formation of cell walls that separate the two daughter cells

Question 7

centriole

Answer 7

rod-like structure constructed of microtubules at the center of each animal cell centrosome

Question 8

centromere

Answer 8

region at which sister chromatids are bound together; a constricted area in condensed chromosomes

Question 9

chromatid

Answer 9

single DNA molecule of two strands of duplicated DNA and associated proteins held together at the centromere

Question 10

cleavage furrow

Answer 10

constriction formed by an actin ring during cytokinesis in animal cells that leads to cytoplasmic division

Question 11

condensin

Answer 11

proteins that help sister chromatids coil during prophase

Question 12

cyclin-dependent kinase

Answer 12

one of a group of protein kinases that helps to regualte the cell cycle when bound to cyclin; functions to phosphorylate other proteins that are either activated or inactivated by phosphorylation

Question 13

cyclin

Answer 13

one of a group of proteins that act in conjunction
