Organization of DNA
Protein-wrapped DNA that forms nucleotides
What are histones?
Chromatin condenses, nuclear envelope disappears, and duplicated chromosomes are present
What is prophase?
Alternating phases of interphase and mitosis
What is the cell cycle?
Body cells that divide by mitosis, diploid, and is found in each parent
Cancer spreads to the rest of the body
What is metastasis?
DNA Duplication
What is S phase?
Broken down into 5 stages
What is mitosis?
Hormone released by cells that stimulate cell growth as a form of cell cycle regulation.
What are growth factors?
Become cancerous through DNA mutations
What are normal cells?
Imbalences within the body caused by poisons and its possible afteraffects.
What is cancer?
The region each sister chromatid are most closely attached
What is the centromere?
A clevage furrow appears due to contractile ring of actin filaments
What is cytokinesis in animals?
Cyclin and Cyclin-Dependant Kinases
What are the key regulators of the cell cycle?
Reproductive cells most of the time, haploid, and divide my meiosis.
What are gametes?
Who is Henrietta Lacks?
Lack of nucleosomes
What creates a lack of chromatin?
2 identical diploid cells
What is the result of mitosis?
The reporduction of cells, growth of cells, and tissue repair.
What is the cell cycle?
Found in all cells to store genetic information
What is a genome?

True
The organization of dna occurs
What is prophase?
Vesices produced by goldi travel to the middle of the cell and form a cell plate
What is cytokinesis in plants?
Shortest stage of the cell cycle
What is mitosis?
Uncontrolable proliferation and are considered immortal
What are cancer cells?
Cyclin concentration is steady throughout cell cycle
