STUDY
PLAY
mitosis
division of the nucleus that creates genetically identical daughter cells
cytokinesis
final step of cell division in which the cytoplasm and organelles are divided into two new cells
interphase
longest stage of cell cycle; cell grows, does its job, and copies DNA
prophase
stage of mitosis in which nuclear envelope and nucleolus disappear and chromatin coils into chromosomes
metaphase
shortest stage of mitosis; spindles attach to centromeres and chromosomes moved to middle of cell
anaphase
stage of mitosis in which chromosomes split and sister chromatids move apart toward opposite poles of the cell
telophase
stage of mitosis in which nucleus splits, nuclear envelope and nucleoli reappear, and chromosomes return to chromatin
cell plate
a developing cell wall that appears in plant cells during telophase
centromere
region on chromosome where sister chromatids attach
spindle fiber
microfilaments that move chromosomes around the cell and assist with cleavage during cytokinesis
cleavage furrow
indentation(s) that indicate splitting of cell in animal cells during telophase and cytokinesis
sister chromatids
the two identical halves of a chromosome that attach at the centromere
cancer
disease that is the result of uncontrolled cell division
carcinogen
a factor that causes cancer; could include chemicals, radiation, viruses, or heredity
tumor
a mass of cancerous cells
benign
a tumor that is encapsulated and not likely to spread
malignant
a tumor that has potential to spread throughout the body
metastasis
the spread of cancer cells throughout the body
mutation
a change in DNA sequence, often caused by carcinogens
chromosome
tightly coiled packets of DNA found in the nucleus during cell division
chromatin
the uncoiled form of DNA that exists during interphase
stem cell
an undifferentiated cell that can become any cell type in the body
differentiation
a process of specialization in which a cell becomes a specific cell type within the body
G1
stage of interphase in which the cell rapidly grows
S-Phase
stage of interphase in which DNA is replicated
G2
stage of interphase in which cell is checked for errors and final preparation for cell division occurs
G0
stage of interphase in which the cell "rests" or stops the division process
apoptosis
programmed cell death that occurs in the cells between fingers and toes and in cells that have been identified as "damaged"
centrioles
rod shaped structures in animal cells that may assist in spindle fiber formation
cell cycle
the sequence of growth (interphase) and division (mitosis) in a cell
