The Cell Cycle
Phase in the cell cycle where the cell is reading the DNA and doing its job
Interphase
Repeating steps a cell goes through in its lifetime
Cell Cycle
During which phase of mitosis do the chromatid arms separate and move to opposite ends of the cell
Anaphase
Relaxed DNA in a non-dividing cell
Chromatin
As a cell grows in size, _______________ increases more rapidly
volume
Cells leave the cell cycle and stop dividing during _________
G0
Cell division that produces two daughter cells that are genetically identical to the parent cell
Mitosis
During which phase do chromosomes line up in the middle of the cell
Metaphase
Constricted area in the middle of a chromosome that holds the two chromatids together
Centromere
What is cytokinesis?
Division of the cytoplasm
List the 3 parts of Interphase
G1, S, and G2
Log- like structures that appear near the nucleus in animal cells and move to opposite poles to pull chromosomes apart
Centrioles
During which phase do the nucleolus and nuclear membrane disappear?
Prophase
Humans have _______ chromosomes or ______ pairs of chromsomes
46; 23
What 3 things happen during Prophase?
List the 3 parts of the Cell Cycle
Interphase, Mitosis and Cytokinesis
Chromosomes that are the same size and shape and carry the same genes but are not identical
homologous chromosomes
During which phase of mitosis do spindle fibers and centrioles disappear?
Telophase
The two identical arms of the chromosome are called ____________________
Chromatids
What type of cells go through Mitosis
Body Cells
Cells spend most of their lifetime in this phase of Interphase
G1
Both involve cell division but cancer is uncontrolled cell division.
What do cells use mitosis for?
growth and repair
Why is it important for DNA to form chromosomes before Mitosis?
Because it is easier to split the chromatids when the chromosomes are in their condensed form.
As a cell grows bigger, the demand on DNA becomes too great. This is called ___________________-
DNA Overload
