Determine the population of bacteria based on the bacterial colonies?
Assume each colony started as a single bacteria in the original culture. Count the colonies you have and multiply up according to how diluted you made the culture and how much of the original culture you used.
What is a bacterial culture containing a single species of organisms referred to as?
A bacterial culture containing a single species of organism is referred to as pure or axenic.
What is a bacterial colony?
Isolated colonies of bacteria are the result of a single bacterium which has replicated many times and eventually formed a visable lump of genetically identical bacteria. The colony's shape, texture and colour can somtimes be helpful in identifying the species of bacteria. For example collonies of Serratia marrceccens are typically pink, moist looking, round and small on nutrient agar. I laymans terms isolated colonies are the single separated spots (normally semi-spherical like zits) on the plate after it has been incubated. If the bacteria are put on the plate too close together they will form a lawn which looks like the whole plate is covered evenly.
What is the function of pound Agar?
LB Broth allows you to create a suspension of bacterial cells from your original colony growing on an agar plate. It provides the necessary nutrients and environment for optimal replication. In suspension, bacterial cells can be plated onto more agar plates, in order to create a streak to cultivate colonies from a single cell, or used to in purification reaction in order to extract the transformed plasmid.
Whether or not a bacterium will be Gram positive is determined by what a the composition of the bacterial cell wall b THE amount of bacterial DNA C the amount of bacterial RNA D the shape of bacteria?
Bacteria are microscopic organisms whose single cells have neither a membrane-bounded nucleus nor other membrane-bounded organelles like mitochondria and chloroplasts. The answer is A

Who hypothesized that a bacterial colony arises from a single bacterial cell?
Robert Koch

What does a single bacterial cell divide into during binary fission?
Binary fission produces two identical bacterial cells.
How you differentiate between Transformed bacterial colonies and satellite colonies?
Re-streak the center of the 'star' colony (transformed surrounded by satellites) on a plate contains the antibiotic, typically ampicillin. The colonies in the tertiary streak will most likely be the transformants. If you want to be quite sure, pick a single colony from the tertiary streak and re-streak again on a plate containing the antibiotic.
Which metric unit when reporting a size of single bacterial cell?
micometers
How many amino acids are attached to a single transfer rna-?
There is only one amino acid that is attached to a single transfer RNA.
Is a bacterial cell the same as a single celled organism?
No, not quite. A bacterium is a single-celled organism, for sure, but not all single-celled organisms are bacteria.
What is bacterial culture?
A laboratory test. bacteria are identified by the appearance of their colonies, by.biochemical tests, and through a Gram stain. bacteria are tested against different antibiotics to determine which will treat the infection by killing the bacteria.
A certain bacterial colony originated from the division of a single bacterial cell Each cell in this colony will most likely?
synthesize the same proteins and enzymes
