|
DNA
|
the genetic material found in all living cells that contains the information needed for an organism to grow, maintain itself, and reproduce
|
|
|
chromosome
|
a structure formed when the DNA in the nucleus of a eukaryotic cell condenses before the cell divides
the physical structure in a cell that contains the cell's genetic material |
|
|
cell cycle
|
the normal sequence of growth, maintenance, and division in a cell
|
|
|
interphase
|
the period in the cell cycle in which a cell grows, maintains itself, and prepares for division
the cell's DNA is copied during interphase |
|
|
mitosis
|
the phase in the cell cycle during which the nucleus divides
|
|
|
prophase
|
chromosomes condense:
nuclear membrane disappears long strands of DNA condense to distinct chromosomes, each with two chromatids that are exact copie |
|
|
metaphase
|
chromosomes line up in the middle of the cell
|
|
|
anaphase
|
chromosomes separate:
chromatids of each chromosome split into two separate chromosomes separated chromosomes pull to the opposite ends of the cell |
|
|
telophase
|
nuclei form; new nuclear membranes form
|
|
|
cytokinesis
|
the division of a parent cell's cytoplasm following mitosis
|
|
|
asexual reproduction
|
the process by which a single organism produces offspring that have the same genetic material
|
|
|
binary fission
|
a form of asexual reproduction by which some single-celled organisms reproduce
the genetic material is copied, and one cell divides into two independent cells that are each a copy of the original cell EXAMPLE: Prokaryotes such as bacteria reproduce by binary fission. |
|
|
regeneration
|
in some organisms, the process by which certain cells produce new tissue growth at the site of a wound or lost limb
a form of asexual reproduction |
