Mitosis And Meiosis Flashcards
(22 cards)
Name the spot that holds the chromatid arms together
Centromere
Name the phase in which spindle fibers and centrioles disappear
Telophase
DNA that is spread out in the nucleus of a non dividing cell is called
Chromatid
Name the phase of the cell cycle in which cells spend most of their time doing their job
Interphase
Name the structures where the spindle fibers grow from
Centrosome
What is the phase of the cell cycle in which the cell makes organelles needed for the new cell
G1 (or Gap 1)
Chromosomes that are the same size, same shape, and carry genes for the same traits are called ___________ chromosomes
Homologous
Name the stage of interphase in which cells copy their DNA
Synthesis
Name the phase of mitosis that follows anaphase
Telophase
Name the phase in which a nucleus is visible and the DNA is spread out as chromatin
Interphase
Name the stage of mitosis in which chromatids separate and move to opposite ends of the cells
Anaphase
TRUE or FALSE - chromatids of a chromosome are identical
True
The micro tubule fibers that pull the chromosomes are called
Spindle fibers
Phase of the cell cycle tht follows G1
Synthesis
Phase in which the nuclear membrane and nucleolus disappear and spindle fibers and centrioles appear
Prophase
Phase of the cell cycle in which the nuclear membrane and nucleolus return
Telophase
Name the three phases (in order) that make up interphase
G1,synthesis,G2
Phase in which the cytoplasm splits
Cytokinesis
What is the dividing wall called
Cell plate
If a cell had a total of 34 chromosomes, how many chromatids does it have?
68
What happens when two homogenous chromosomes pair up with each other during prophase 1 in meiosis
Synapsis
What is it called when some chromatids are very close to each other and segments cross
Crossing over
