Micro212 EXAM 1
BCCC- MICROBIOLOGY- PROFESSOR NORRIS
| Question | Answer |
|---|---|
| WHAT ARE EXAMPLES OF ACELLULAR MICROBES? | viruses, viroids and prions |
| WHAT ARE THE FIVE KINGDOMS | MONERA(PROKARYTOIC),PROTISTA,FUNGI,PLANTAE,ANIMALIA(EUKARYOTIC) |
| WHAT IS PROKARYOTICS | HAS NO MEMBRANE ORGANELLE,NO NUCLEUS, USES BINARY FUSION, AND SINGLE CIRCULAR CHROMSOMES |
| WHAT IS EUKARYOTICS | HAS A MEMBRANE ORGANELLE, HAS A NECLEUS, USES MITIOSIS, LINEAR CHROMOSOMES |
| WHAT THING DO PROKARYOTIC AND EUKARYTOICS HAVE IN COMMON | THEY BOTH HAVE CELL WALL, LIVING,PLASMA MEMBRANCE, FLAGELLA, DNA, AND HAS CYTOPLASM |
| WHAT BACTERIA DOESN'T HAVE A CELL WALL AND TENDS TO BE PLEOMORPHIC | MYCOPLASMA |
| WHAT IS PASTEUR KNOWN FOR | DISPROVING SPONTANEOUS GENERATION, COMING UP THE VACCINES FOR RABIES, DISCOVER FERMENTATION |
| WHAT IS ROBERT KOCH KNOWN FOR | FINDING THE AGENT ANTHRAX FROM THE BACTERIA KNOWN AS BACILLUS |
| WHO WAS ANTON VON LEEUWENHOOK | THE FIRST TO DISCOVER MICROBES AND THE FIRST TO USE A MICROSCOPE. HE NAME THEM FIRST AS ANIMALIA |
| WHO WAS EDWARD JENNER | WAS THE FIRST TO USE COWPOX TO PROTECT AGAINST SMALLPOX |
| WHAT WAS JOSEPH LISTER KNOWN FOR | THE FIRST TO USE ASPECTIC TECHIQUE IN THE O.R |
| WHAT WAS PAUL EHRLICH KNOWN FOR | THE FIRST TO USE CHEMICAL TO FIGHT INFECTOUS DISEASE LATER KNOWN AS CHEMOTHERAPY |
| WHO WAS SIR ALEXANDER FLEMING | THE FIRST TO USE THE ZONE OF INHIBITON USING PENICILLIUN |
| WHAT IS GRAM (+)BACTERIA | HAS A GLYCINE INTERBRIDGE AND HAS THICK WALLS |
| WHAT IS GRAM(-) BACTERIA | HAS PEPTOGLYCAN MADE UP OF 2 SUGARS CALLED (NAG & NAM)WHICH HAS A DIRECT PEPTIDE BOND, AND HAS THIN WALL.(LPS MAKES GRAM (-) BACTERIA MORE TOXIC BECUASE OF LIPID-A ACTS AS A ENDOTOXIN |
| WHAT ARE EXAMPLES OF EUKARYA | ANIMALS, PLANTS, FUNGI, PROTISTA |
| NAME THE DOMAINS | EUBACTERIA,EUKARYA,ARCHAEA |
| PHASE- CONTRAST MICROSCOPE | USED TO SEE INTERNAL STRUCTURES IN TRANSPARENT LIVING CELLS |
| DARK FIELDS MICROSCOPE | USES ABBE CONDESOR, BACKGROUND APPEARS DARK AND OBJECT IS LIGHT USED TO SEE SPRIOCHETE AND SYPHILIS |
| FLUORSCENCE MICROSCOPE | USES UV RAYS AND PROTECTIVE FILTER MICROBES ARE TREATED WITH FLUOCHROMES. LOW NUMBERS OF BACTERIA CAN BE FOUND |
| WHAT DISEASE CAN BE SEEN WITH A FLUROSCENCE MICROSCOPE | TB |
| TRANSMISSION ELECTRON MICROSCOPE (TEM) | USED TO SEE INTERNAL STRUCTURE UP TO 500,000X, HAS A CASTING SHADE AND OBJECTS SHOW IN GRAY |
| SCANNING ELECTRON MICROSCOPE | USED TO SEE INTERNAL STRUCTURE YP TO 50,000X, USES 3-D IMAGES TO DETERMINE MORPHOLOGY, ARRAGMENT, AND ATTACHMENTS CELL |
| ATOMIC FORCE MICROSCOPE | USES NEEDLE TO FORCE ATOMS WITHIN MICROBE TO GIVE IMAGE |
| WHAT IS THE MAIN USES OF THE ATOMIC FORCE MICROSCOPE | TO LOOK AT DNA STRUCTURES AND CELL SURFACES |
| WHAT IS ASSIOCATED WITH ARCHEA | BACTERIA WITH EXTREME LIVING ENVIRNOMENTS |
| WHAT IS ASSICATED WITH EUBACTERIA | BACTERIA ASSIOCATED WITH HUMANS |
| WHAT IS ASSIOCATED WITH EUKARYA | PLANTS, ANIMALS, PROTISTA, FUNGI |
| WHAT IS THE CELL WALL AND IT'S FUNCTION AND PURPOSE | PROTECTS AGAINST OMOTIC SHOCK, CONTAINS COMPONENTS THTAT CONTRIBUTE TO PATHOGENCITY, IS THE SITE OF ACTION OF SEVERAL ANTIBOTICS, AND CAN NOT BE SEEN ON A BRIGHTFIELD MICROSCOPE |
| AGENTS THAT WILL DESTROY CELL WALL | PENICILLIN AND LYSOZYME |
| THE ACTION OF PENICILLIN ON THE CELL WALL IS | IT INHIBITS PEPTIDE BOND FORMATION |
| WHAT IS BACULLUS ANTHRACIS CAPSULE MADE UP OF | POLY - D- GULTAMIC |
| WHAT IS THE FUNCTION OF CAPSULES AND WHAT ARE THEY MADE UP OF | TO PROTECT BACTERIA AGAINST TOXICS AND DETERGENTS AND THEY ARE MADE OF POLYSACCHARDIES |
| WHAT IS TRANDUCTION | TRANFER OF DNA FROM BACTERIA TO BACTERIA BY A VIRSUS |
| WAHT IS TRANFORMATION | is the genetic alteration of a cell resulting from the uptake, genomic incorporation, and expression of foreign genetic |
| WHAT IS RECOMBINATION | Genetic recombination is the process by which a strand of genetic material (usually DNA; but can also be RNA) is broken and then joined to a different DNA |
| WHAT IS CONJUGATION | is the transfer of genetic material between bacteria through direct cell-to-cell contact |
| WHAT IS PILI OR FRIMBRIA | THEY ARE COMPOSED OF OLINGOMERIC PROTEINS USED FOR ATTACHMENT FOR BACTERIA CONJUGATION |
| WHAT IS THE S LAYER AND IT'S FUNCTION | IT'S SEEN IN GRAM (+) AND GRAM(-)CELLS IT PROTECTS AGAINST PHAGOCYTOSIS AND PROMOTES ADHESION. IT ALSO PROTECT AGAINST ION AND PH FLUCTATIOIN AND BACTERIA LIKE BDELLOVIBRIO |
| WHAT IS FLAGELLA | COFlagella are long, thread-like appendages which provide some live single cells with the ability to move, motility. |
