The Microbial World
These particles are not living, but are comprised of proteins and nucleic acid.
Virus
When using a standard compound light microscope, the objective is 100X what is the total magnification of the Field of view?
1000X
The sequence of nucleotides that codes for a specific amino acid is called a
Codon
This technique is used to prevent contamination of cultures and the immediate enviornment.
Aseptic Technique
This is process of briefly exposing perishable items to high temperatures to reduce microbial load.
Pasteurization
These organisms are prokaryotic but lack peptidoglycan and usually are found in extreme environmental conditions
Archaea
This microscope scans the surface of small particles using the discharge of secondary electrons to generate and visualize a picture of the surface
Scanning electron Microscope
The promoter
This phase is the initial phase of bacterial growth curve where bacterial growth is minimal as the bacteria adapts to the new environment
Lag Phase
This terminology is used to define the process of removing all microbes from the object or immediate environment.
Sterilization
These infectious protein particles cause disease but are not living
Prions
This terminology is used to determine the ability to distinguish two different adjacent points is called
Resolution
The site that regulates the activity of RNA polymerase on the operon is called the...
Operator
These types of bacterial organisms thrive in frigid temperatures with ideal temperatures ranging from -5 to 15 degrees celsius.
psychrotroph
These infections are acquired in the hospital
Nosocomial Infections
Bacterial organisms that colonize healthy individuals and usually aid the host instead of causing disease are part of the hosts __________ __________
Normal Flora
This form of microscopy blocks direct light from passing through the specimen often allowing the visualization of unstained specimens to be seen using indirect light.
Dark field microscopy
The Lac Operon is considered to be an ____________ Operon.
Inducible
These bacteria can survive in an environment with or without the presence of oxygen.
facultative anaerobe
This apparatus is used to sterilize equipment by raising the temperature to 121C and applying 15-PSI
Autoclave
This is the process of using microorganisms to hasten the decay of pollutants
This microscope transmits electrons through a thinly cut specimen allowing for the visualization of dense and nondense regions.
Transmission electron microscope
regarding gene regulation, enzymes that are usually turned on, but at times can be turned off are called ___________ enzymes.
This type of media contains substances that allows bacteria to grow in an identifiable way.
differential media
This gaseous compound is used to sterilize medical equipment in mass amounts (requires air-tight chamber and 12 hours of incubation for sterility)
