cell cycle regular pattern of growth, DNA duplication, and cell division that occurs in eukaryotic cells

cytokinesis process that divides the cell cytoplasm
chromosome one long continuous thread of DNA that consists of numerous genes along with regulatory information
histone group of proteins that chromosomes are associated with that DNA wraps around
chromatin loose combination of DNA and proteins
chromatid one half of a duplicated chromosome, that when is combined with its identical is called sister chromatids
centromere region of condensed chromosome that looks pinched and holds sister chromatids
telomere made of repeating nucleotides that do not form genes and prevents the ends of chromosomes from accidentally attaching to each other, and helps prevent the loss of genes
prophase chromatin condenses into tightly coiled chromosomes that consists of two identical sister chromatids
metaphase spindle fibers attach to a protein structure on the centromere of each chromosome and align the chromosomes along the cell equator, around the middle of the cell
anaphase sister chromatids separate from each other
telophase complete set of identical chromosomes are positioned at each pole of the cell
growth factor broad group of proteins that stimulate cell division
apoptosis programmed cell death
cancer common name for a class of diseases characterized by uncontrolled cell division
benign tumor cancer cells typically remain clustered together

binary fission asexual reproduction of a single-celled organism by division into two roughly equal parts
tissue groups of cells that work together to perform a similar function
organs groups of tissues that work together to perform a specific function or related functions
organ systems organs that carry out similar functions
cell differentiation process by which unspecialized cells develop into their mature forms and functions
stem cells unique type of body cell that have the ability to, 1. divide and renew themselves for long periods of time, 2. remain undifferentiated in form, 3. develop into a variety of specialized cell types
