Final Bio Lab Quiz
| Question | Answer |
|---|---|
| Asexual Reproduction | Involves one organism/cell; nucleus divides evenly into two copies, one for each cell |
| Sexual Reproduction | Involves 2 organisms/cells each giving half of genetic material |
| DNA | Double stranded polymer that encodes genetic information for an organism |
| Genes | Segment of DNA |
| Genome | Complete set of DNA for an organism |
| Chromosomes | Structures of DNA and proteins that help organize DNA |
| Chromatids | Half of a duplicated chromosome |
| Centromere | Region of connection to sister chromatids |
| Somatic Cells (A Type of Cell in a Eukaryote) | Form the body, organs of the organism |
| Gametes (A Type of Cell in a Eukaryote) | Reproductive cell that has half of the copies of each gene |
| 2 Phases of Cell Cycle | Interphase - Cell grows and prepares to divide; most of cell's life is spent here. Mitotic Phase - Process of Cell Division (mitosis and cytokenisis) |
| 3 Phases of Interphase | G1 - Normal functions S - Chromosomes are replicated G2 - Continued growth and preparation for division |
| 4 Phases of Mitosis | Prophase - Condensing of chromosomes Metaphase - Sister chromatids line up Anaphase - Sister chromatids separate Telophase - chromosomes are at poles and expanding |
| Cytokenesis | Cell plate forms that divides the cytoplasm, forming the two daughter cells |
| Images of Stages of Mitosis | . . . . . |
| Cancer | Unrelated cell growth/division that causes tumors that interfere with organ functions to develop and spread |
| Causes of Cancer | Proto-oncogenes (=gas pedal), tumor suppressor genes (=break) |
| Skin Cancer Look For: | Asymmetry, border, color, diameter |
