U5 Cell Cycle and Cancer
Definition | Term |
---|---|
Process of cellular reproduction, occurring in three main stages- interphase, mitosis, and cytokinesis. | Cell Cycle |
First stage of the cell cycle, during which a cell grows, matures, and replicates DNA. | Interphase |
DNA-containing structure that carries genetic material from one generation to another. | Chromosome |
Twisted-ladder shape of DNA, formed by two nucleotide strands twisted around each other. | Double Helix |
A subunit of nucleic acid formed from a simple sugar, a phosphate group, and a nitrogenous base. | Nucleotide |
Enzyme that catalyzes synthesis of new DNA molecule | DNA Polymerase |
Structure that contains identical DNA copies and is formed during DNA replication. | Sister Chromatids |
Cell structure that joins two sister chromatids. | Centromere |
The creation of two strands of DNA from a parental template DNA strand. | Replication |
The stage of the cell cycle during which the cell’s nucleus and nuclear material divide. | Mitosis |
First stage of mitosis, during which the cell’s chromatin condenses into chromosomes. | Prophase |
Second stage of mitosis in which motor proteins pull sister chromatids to the cell’s equator. | Anaphase |
Third stage of mitosis in which sister chromatids are pulled apart and microtubules, along with motor proteins, move the chromosomes to opposite poles of the cell. | Metaphase |
The last stage of mitosis in which nucleoli reappear. Two new nuclear membranes begin to form, but the cell has not yet completely divided. | Telophase |
Third main stage of the cell cycle, during which the cell’s cytoplasm divides creating a new cell | Cytokinesis |
Uncontrolled growth and division of cells that can be caused by changes in control of the cell cycle and also may be caused by environmental factors. | Cancer |
