Biology

2. reproduction Process by which offspring are produced from a single parent; does not involve the joining of gametes.
6. Common name for a class of diseases characterized by uncontrolled cell division
7. Loose combination of DNA and proteins that is present during interphase.
8. that organizes chromosomes and around which DNA wraps.
9. fission Asexual reproduction in which a cell divides into two equal parts.
12. Second phase of mitosis when spindle fibers align the chromosomes along the cell equator.
13. Programmed cell death.
16. Last phase of mitosis when a complete set of identical chromosomes is positioned at each pole of the cell, nuclear membranes start to form, the chromosomes begin to uncoil, and the spindle fibers disassemble.
17. Process by which cell divides its nucleus and contents.
18. Long, continuous thread of DNA that consists of numerous genes and regulatory information.
19. third phase of mitosis which chromatids separate and are pulled to opposite sides of the cell.
20. Region of condensed chromosome that looks pinched; where spindle fibers attach during meiosis and mitosis
21. Having no dangerous effect on health, especially referring to an abnormal growth of cells that are not cancerous
22. Process by which the cell cytoplasm divides.

1. Process by which unspecialized cells develop into their mature form and function.
3. First phase of mitosis when chromatin condenses, the nuclear envelope breaks down, the nucleolus disappears, and centrosomes and centrioles migrate to opposite sides of the cell.
4. Cancerous tumor in which cells break away and spread to other parts of the body; causing harm to the organism's health.
5. To spread by transferring a disease-causing agent from the site of the disease to other parts of the body.
10. One half of a duplicated chromosome
11. Broad group of proteins that stimulate cell division.
14. Repeating nucleotide at the ends of DNA molecule that do not form genes and help prevent the loss of genes.
15. Cell that can divide for long periods of time while remaining undifferentiated.
18. Substance that produces or promotes the development of cancer.
20. Cycle Pattern of growth, DNA replication, and cell division that occurs in a eukaryotic cell.
