One of the two identical sister parts of a duplicated chromosome.
Area where the chromatids of a chromosome are attached.
Dioxyribonucleic acid, carries the directions for inheritance.
Threadlike substance within the nucleus that contains the genetic information passed from one generation of cells to the next.
Process by which the number of chromosomes per cell is cut in half, through the separation of homologus chromosomes in a diploid cell.
Process by which a cell divides into two new daughter cells, PMATC
IPMATC, series of events that cells go through to grow and divide.
Period of cell cycle between divisions, (growth and replication of DNA)
First and longest phase of mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on oppoite ends of the nucleus.
Used to refer to a cell that contains only a single set of chromosomes and therefore only a single set of genes.
Second phase of mitosis, when chromosomes line up along the center of the cell.
Third phase of mitosis, during which the chromosome pairs separate and move toward opposite poles.
Fourth and final phase of mitosis, during which the chromosomes begin to disperse into a tangle of dense material.
Division of the cytoplasm
Cell that contains both sets of genetic information.
Part of eukaryotic cell division during which the cell's nucleus divides.
Two tiny structures located in the cytoplasm of animal cells near the nuclear envelope.
Disorder in which some of the body's own cells lose the ability to control growth.
One of a family of closely related proteins that regulate the cell cycle in eukaryotic cells.
Chromosomes that each have a cooresponding chromosome from the opposite sex parent.
Proteins that respond to events within the cell.
Proteins that respond to events outside of the cell.
Specialized cel involved in sexual reproduction.
Is interphase an actual phase of mitosis?
Phase of interphase in which the DNA or chromosomes are replicated.
Phase of interphase in which the cell grows.
They respond by not growing.
What happens when growing cells come in contact with other cells?
They will begin dividing until they fill the empty space.
If growing cells are removed from the petri dish, what occurs?
Mass of tissue caused by cancer.
Cells do not increase in ____, they increase in ______.
This letter represents the number of chromosomes in a gamete.
Chromosome arms exchange DNA segments when homologus chromosome pairs are next to eachother.
Which phase does crossing over occur in? (Meiosis)
Period when cell prepares to divide,after DNA is duplicated.
Two identical halves of a chromosome
Process by which prokaryotic cells duplicate.
Number of chromosomes in a human.
When chromosomes condense.
When the nucleus is completely formed, this begins to appear.
