Cards

Term
Mitosis
Definition
Making identical copies of regular body cells (ex: skin cells)
Term
Chromosome
Definition
A package of DNA wound tightly around proteins.
Term
Centromere
Definition
The part that connects the two sister chromatids (copies of chromosomes after DNA replication)
Term
Spindle
Definition
Cell part that pulls chromosomes around the cell.
Term
Diploid Cell
Definition
A cell that has two sets of chromosomes (one from each biological parent)
Term
Haploid Cell
Definition
A cell that contains only one set of chromosomes (half the normal number)
Term
Cell Cycle
Definition
The life cycle of a cell that contains cell growth, cell part replication, and cell division.
Term
Interphase
Definition
Phase of cell cycle when the cell is growing and carrying out its purpose (ex: red blood cell carrying oxygen)
Term
Prophase
Definition
Phase of cell cycle in which chromosomes are visable; nucleus breaks down, spindles form
Term
Homologous Chromosomes
Definition
A pair of chromosomes that have the same genes for the same traits; you get one from each biological parent
Term
Metaphase
Definition
Phase of cell cycle in which chromosomes line up down the middle of the cell along the spindles
Term
Anaphase
Definition
Phase of cell cycle in which sister chromatids are pulled apart.
Term
Telophase
Definition
Phase of cell cycle in which two nuclear membranes form around the chromosomes
Term
Cytokinesis
Definition
Final stage of cell cycle in which the cell divides down the middle creating two new cells.
Term
Sister Chromatids
Definition
Identical copies of chromosomes made during DNA Replication
Term
Gamete
Definition
Reproductive Cells (example: sperm, egg, pollen)
Term
Meiosis
Definition
Making reproductive cells
Term
Centriole
Definition
Cell part that produces spindles (like spider man waiting until his webs are needed)
Term
Crossing Over
Definition
During Prophase I of meiosis, homologous chromosomes match up and exchange genetic information assuring each daughter cell is genetically different
