Chromosomes
long, continuous thread of DNA that consists of numerous genes and regulatory information, condense at the start of mitosis
chromatid
one of two identical "sister" parts of a duplicated chromosome, one half
centromere
Region of a chromosome where the two sister chromatids attach
telomere
DNA at the tips of chromosomes, caps on the end of the dna that help protect it
DNA
deoxyribonucleic acid, wraps around proteins called histones, forming chromatin
chromatin
condenses and coils creating a chromosome, made of dna and histones(proteins)
histone
protein molecule around which DNA is tightly coiled in chromatin
cell cycle
the regular pattern of growth, DNA duplication, and cell division that occurs in eukaryotic cells, g1, s phase, g2, mitosis
interphase
g1, s(synthesis), g2, prepares the cell to divide, chromosomes are invisible but copy themselves and centrioles are copied
mitosis
includes division of cell nucleus and division of the cytoplasm
centriole
move to opposite poles to aid in cell division
spindle fibers
form in prophase, attach to each chromosome in metaphase, and pull chromosomes apart in anaphase
centriole
