Unit 1 Biology
Germ Theory, Viruses, Diseases, etc
Term | Definition |
---|---|
Lysogenic Infection | Process in which viral DNA becomes part of a host cell's DNA |
Prion | Misfolded protein that causes disease in animals |
Bacteriophage | Virus that infects bacteria |
Antibiotic | Compound that can block the growth and reproduction of bacteria |
Virus | A particle made of genetic material and a capid that can replicate only by infecting living cells |
Prokaryote | Organism consisting of one cell that lacks a nucleus |
Prophage | Bacteriophage DNA that is embedded in the host's DNA |
Pathogen | Disease-causing microorganism |
Lytic Infection | Process in which a host cell bursts after being invaded by a virus |
Endospore | Protective structure formed by a prokaryote when growth conditions are unfavorable |
Binary Fission | How bacteria reproduce; Process in which a bacterium replicates its DNA and divides in half |
Vaccine | Preparation of weakened or killed pathogens or inactivated toxins used to produce immunity |
Capsid | A protein surrounding a virus |
Ribovirus | Viruses that have RNA as their genetic material |
SARS, MRSA, Ebola, and bird flu are all example of this | Viral Infection / Disease |
Robert Koch | Identified the specific microbes that caused diseases and came up with four postulates |
Ignaz Semelweiss | Many women were dying during childbirth, becuase of something called "childbed fever" so he came up with the idea that doctors should wash their hands before delivering babies |
Edward Jenner | Developed a vaccine against smallpox after observing that people who got cowpox did not get smallpox |
Louis Pasteur | Developed "germ theory" which proposed that specific microbes acted as disease fighting agents |
Robert Hooke | Developed his own microscope and invented the term "cell" |
Antoni van Leewenhoek | One of the first to observe microbes (living, moving, microorganisms) |
Rudolph Virchow | All cells come from other cells. All diseases are caused by cell that do not work properly. |
Joseph Lister | After research, he introduced sterilizing clothing and equipment in surgery |
This theory states that pathogens are what causes disease | Germ Theory of Disease |
Flagellum | what bacteria uses to move |
Viroid | infectious RNA that passes through seeds or pollen to cause disease in plants |
Rod-shaped prokaryotes | bacilli |
Spiral-shaped prokaryotes | spirilla or spirochetes |
Round-shaped (spherical) prokaryotes | cocci |
Antibiotics | Chemicals that kill or slow the growth of bacteria. It only works on living things without a cell wall (AKA humans). |
Another name for a disease-causing agent | Pathogen |
Infectious Disease | A disease carried by a pathogen that is transmitted from organism to organism |
The Use of Koch's Postulates is... | To identify the cause of a certain disease |
What is the treatment for pathogens? | Prevention |
What is the treatment for protists (malaria)? | Chloroquine and ACTs (artemisinin-based combination therapy) |
What is the treatment for bacteria? | Antibiotics |
What is the treatment for viruses? | Vaccines |
Conjugation | The transfer of genetic material between two prokaryotes; A process in which some bacteria exchange genetic material |
Prokaryote | A unicellular organism that lacks a nucleus. Classified into bacteria and archaea. |
Endocytosis | How a virus gets inside a cell |
Lysogenic Cycle | The viral DNA combines with the host DNA. Whenever the cell divides, the virus is copied into daughter cells. A trigger causes the Lytic Cycle to start |
Lytic Cycle | When viral DNA takes over and uses energy from the host to reproduce |
