More Mitosis
100
When the chromosome pairs separate and move towards opposite poles...
What phase is Anaphase?
100
The two identical parts of a duplicated chromosome.
What is a Chromatid?
100
The process by which a cell divides into two "daughter" cells...
What is Cell Division? (or mitosis)
100
Where the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus...
What is Prophase?
100
How is cell size related to DNA?
If a cell becomes too big, there is too much demand on the DNA (overload)
200
The four phases of the cell cycle are...?
G1, S, G2 and M
200
Series of events that cells go through as they grow and divide.
What is the Cell Cycle?
200
What happens as cells grow bigger?
The cell has more trouble moving enough nutrients and wastes across the cell membrane.
200
Period of a the cell cycle between cell divisions...
What is Interphase?
200
1. All living things are made of cells... 2.The cell is the basic unit of life... 3.Cells come from preexisting cells...
What is the Cell Theory?
300
A fanlike microtubule structure that helps separate the chromosomes during mitosis.
What is a Spindle?
300
Tiny structures that produce and keep the spindle fibers anchored in place.
What are centrioles?
300
The division of cytoplasm...
What is cytokinesis?
300
A period of activity in which cells do most of their growing...
What is the G1 phase of interphase?
300
The cell goes through the cell cycle to divide when this happens...
What happens when a cell gets too big?
400
The phase in which the chromosomes uncoil back into chromatin, and two nuclei form
What is Telophase?
400
A disorder in which some of the body's own cells lose the ability to control growth.
What is Cancer?
400
The division of the cell nucleus...
What is Mitosis?
400
Many of the organelles and molecules required for cell divisions are produced.
What is the G2 phase of interphase?
400
The difference between chromatin and a chromosome...
Chromosomes are supercoiled/very condensed and are only visible during mitosis. Chromatin is loosely coiled and visible during interphase
500
Where chromatids are attached...
What is a Centromere?
500
A cell has to "pass through" these in order to get the go ahead to divide
What are checkpoints?
500
Cytokinesis and Mitosis are...
What are the two main stages of Cell Division?
500
Chromosomes are replicated and the synthesis of DNA molecules takes place...
What is the S phase of interphase?
500
If a cell has 38 chromosomes at the beginning of interphase, how many will it have at the end of interphase, before mitosis begins?
