Prophase
The phase of the cell cycle occurring before prophase
Interphase, more specifically G2
What connects sister chromatids?
Centromeres
Is there a cell checkpoint before or after anaphase?
Before
What results from telophase?
Two identical daughter cells
What happens after telophase?
Cytokinesis- the cytoplasm splits and two daughter cells form
Name a process that occurs during prophase.
The spindle fibers form, the nuclear membrane breaks down, chromatin condenses and the nucleoli disappear
Name a process that occurs during metaphase.
Spindle fiber connect to sister chromatids from the centriole, chromosomes line up in the center
Name a process that occurs during anaphase
Sister chromatids disconnect and are pulled to either side of the cell
Name a process that occurs during telophase
Two nuclei form, chromosomes de-condense, and the nucleoli reappear
Name a phase in the cell cycle in which the cell would initiate a checkpoint and the name of that checkpoint
G1, G2, and M checkpoints. G1 occurs during interphase before synthesis, G2 after synthesis and M checkpoint during mitosis, specifically metaphase
How many sister chromatids and how many chromosomes are there in a human cell entering prophase
46 chromosomes and 92 chromatids
What is the name of the protein that connects the spindle fibers to the sister chromatids?
Kinectochore
What can go wrong during anaphase?
The m checkpoint gave the go ahead even though a spindle fiber didn't reach a chromosome
What is a cleavage furrow?
An indentation that appears on the cell membrane when the cell is preparing to divide
What happens if after telekinesis the cell does not initiate cytokinesis?
The single cell would have two nuclei
Extra: what does telos mean in latin?
End
Tiebreaker: what is the name of reproductive cells in general
Gametes
