Viruses and Bacteria
SLS-Bio11
| Question | Answer |
|---|---|
| Antibody | Any one of the y shaped gamma goblin proteins found in the blood or lymph, and produced by B cells as an immune defence mechanism against antigens. |
| Antigen | A substance that enters the body and starts a process that can cause disease. (Antibodies then fight this off) |
| DNA | A macromolecule known as a nuclei acid , shaped as a double helix with long sugar and phosphate groups along with nitrogenous bases ATGC |
| Host cell | An animal or plant on or in which a parasite or commensalism organism lives |
| Lymposyte | The white blood cell of the blood derived from the stem cells of the lymphoid series of vertebrates. |
| Lysogenic cycle | A viral reproduction involved by integration of the bacteriophage nucleic acid into the host bacterium so genome or formations of a circular replicant in the bacterium so cytoplasm |
| Lytic cycle | The main method of viral reproduction because it ends in the lysis of the infected cell releasing the progeny viruses that will in turn spread and infect other cells |
| Membranous envelope | A double layer of lipid, contains proteins that surrounds biological cells |
| Mucous membrane | An epithelial tissue that secretes mucous and that lines many body cavity a and tubular organs |
| Nucleic acid core | It is a core that which is part of a nuclear reactor where binary fission occurs |
| Phagosytic white blood cell | Cells that protect the body by ingesting harmful foreign particles, bacteria and dead or dying cells. |
| Line of defence | A line of defence that protects the cell, the skin, lysozymes, blood clotting, mucous and cillia, and the cell wall are lines of defence |
| Primary line of defense | Usually having first, direct contact external environment. |
| Protein Capsid | The capsid is the protein shell of any virus. Made up of many oligomrric structural subunits called protomers |
| RNA | Ribonucleic acid that is present is all living cells. It is the messenger of the cell carri g instructions from Dna for controlling the synthesis and proteins |
| Secondary line of defense | A group of cells, tissues and organs that work together to protect the body (immune system) |
| Tertiary line of defense | Anything such as antibodies, antigens or any invaders that pass through the first and second line of defence |
| Viral speciacity | A virus is selective in the organisms it infects, the type of cells and the disease it produces |
| White blood cell | Fighting blood cell ( leukocyte ) |
| Aerobic respiration | "With air" breathing where oxygen is needed |
| Antibiotic | A medicine that inhibits the growth of or destroys micro organisms |
| Antiseptic | Substances that prevent the growth of disease-causing micro organisms |
| Binary fission | Is a kind of asexual reproduction, most common use of reproduction in prokaryotes |
| Classification | The process of classifying something according to shared equalities or characteristics |
| Conjugation | The formation or existence of a link or connection between things in particular. |
| Disinfectant | A chemical liquid that destroys bacteria |
| Ecological role | A niche and position a species has in its environment |
| Fermentation | A metabolic process that converts sugars to acids, gases or alcohol it occurs in yeast and bacteria |
| Motate | To move from one location to the next |
| Mutate | Change or cause to change in form or nature |
| Mutation | The action or process of mutating from something harmul |
| Photosynthesis | The act plants do to get energy from the sun |
| Prokaryote | A microscopic single called organism with only one district nucleus with a membrane |
| Resistant/Resistance | The refusal to accept or comply with something, the ability to be affected by something |
