| Question | Answer |
|---|---|
| Embryotic | have the most potential |
| Zygote | fertilized egg. |
| DNA in eukaryotic chromosomes | help regulate gene expression by preventing access of transcription proteins to the DNA. |
| Nuclear Transplantation | can be used to clone animals and is the most common cloning technique. |
| 2 types of cloning | Reproductive & therapeutic (tissue) |
| Reproductive cloning of nonhuman mammals is useful in | research, agriculture, and medicine. |
| Sexual Reproduction | fertilization of sperm and egg produces offspring. |
| Asexual Reproduction | offspring produced by a single parent |
| Pre-existing cells | Where cell arise from |
| Binary fission | occurs in prokaryotic cells and protists, reproduces asexually by cell division. |
| Chromosomes | contain a very long DNA molecule associated with proteins and are visible only when the cell is in the process of dividing. |
| Chromatin | a cell that is not undergoing division, chromosomes occur in the form of thin. |
| Sister chromatids | two identical copies joined together at the centromere. Before cells start dividing. |
| Interphase | Is where the bulk of the cel cycle time is spent. |
| 3 stages of Interphase | G1, G2, S |
| Cytokinesis & Mitosis | Are in the mitotic phase |
| 5 mitotic parts | Prophase, prometaphase, metaphase, anaphase, and telophase. |
| Spindle fibers | an array of microtubules and proteins that form between the opposite poles of the cells. |
| Centrosomes | are the regulator of the cell cycle progression |
| Metaphase plate | an imaginary plane equal distance from both poles. |
| Cytokinesis | overlap mitosis |
| 3 purpose of mitosis | Growth, Replacement of the damaged or lost cells, asexual reproduction. |
| Anchorage dependente | is defined as normal cells that divide only when attached to a surface |
| density dependent inhibtion | when cells have formed a complete single layer, they stop dividing |
| Growth Factor | are proteins secreted by cells that stimulate other cells to divide. |
| Apoptosis | programmed cell death |
| Tumors | an abnormal growth or mass of tissue. Malignant and benign |
| Metaphasis | occcurs when tumor cells have moved to a different part of the body from the original place. |
| Maligngant tumors | serve and progressively worsening tumors that can invade or metastasis |
| Radiation, chemotherapy, and surgery | 3 types of cancer therapy |
| Biopsy | a surgical procedure to find out if the tumor is cancerous by removing some sample tissue for examination. |
| 2 types of procedures for a biopsy | Incisional: take piece of tumor Excisional: take entire tumor |
| Proto-oncogene | a normal gene that promotes cell division |
| Oncogene | causes cells to divide excessively |
| Etilogy | study of what causes diseases. |
| 2 major components of etiology of cancer is: | Genetic & Environmental |
| Mutations & tumor-suppressor genes | will cause similar effects as oncogenes. |
| Precipitating factor | something that causes a family that's predisposed to get cancer. |
