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.

What was true about the American colonies after the Continental Congress met?
The American Revolution transformed thirteen British colonies into fourteen states.
What is the most common shape of bacterial deep colonies?
The most common shape of bacterial deep colonies is typically circular or dome-shaped. These colonies often display a smooth, raised appearance, although variations exist depending on the bacterial species and growth conditions. The circular shape allows for efficient growth and nutrient absorption in the available medium.
In what ways do the macroscopic features of bacterial colonies differ from that of molds?
Bacteria looks more glossy, white or yellow Molds will have a fuzzy look to them
What was the name of the document that turn the thirteen colonies into the US?
The document that transformed the thirteen colonies into the United States was the Declaration of Independence, adopted on July 4, 1776. It proclaimed the colonies' separation from British rule and outlined the principles of individual rights and government by consent. This foundational text established the United States as a sovereign nation.
How dilution of sample is achieved with the major technique for isolation of bacterial colonies?
Dilution of a sample for the isolation of bacterial colonies is primarily achieved using the serial dilution technique. In this process, a sample is sequentially diluted in a sterile liquid medium, typically by transferring a small volume of the sample to a larger volume of diluent, such as saline or nutrient broth. This method reduces the concentration of bacteria, allowing for the separation of individual cells when plated on solid media. As a result, the colonies that develop on the agar surface can be counted and isolated for further study.
Do yeast colonies resemble bacterial or fungal colonies?
bacterial
What does the phenotype of the transformed colonies tell you?
The phenotype of the transformed colonies can reveal information about the characteristics conferred by the introduced foreign DNA. It may indicate traits such as antibiotic resistance, fluorescent protein production, or enzyme activity, depending on the gene that was inserted. This can help confirm successful transformation and expression of the desired gene in the bacterial colonies.
What is non selective media?
Non-selective is when we use agar for bacterial growth in general. Mean not to differentiate between them but just to see their colonies and growth. TSA and Chocolate agar are nonselective.
What are the problems with agar plates?
Agar plates can become contaminated with unwanted microorganisms, leading to inaccurate results. They can also dry out, affecting the growth of bacteria. Additionally, agar plates can become overcrowded with bacterial colonies, making it difficult to differentiate and count individual colonies.
Yeast colonies larger than bacterial colonies?
Not necessarily, some Bacillus can have big colonies
Are satellite colonies sensitive to ampicillin?
Yes, satellite colonies may be observed radiating from the edges of large, well-established colonies. These satellite colonies are not ampicillin-resistant, but grow in an "antibiotic shadow", where ampicillin in the media has been broken down by the large resistant colony. Satellite colonies are generally a sign of antibiotic weakened by not cooling medium enough before adding antibiotic, long-term storage of more than 30 days, or overincubation.
How were the colonies transformed into sovereign states?
(by forming their own governments)
Why GFP colonies are observed in the plate with pQE30 and GFP construct?
Go to http://www.tsienlab.ucsd.edu/Images.htm you will find bacterial colonies will and can express functional fluorescent proteins. As for the plasmid pQE30, it looks to fit into the category of expression at this level.
How to determine Bacterial load?
By pour plate and then counting the colonies.
Do all bacterial colonies consist of pure cultures?
YES.!!
How many bacterial colonies are in a guinea pig mouth?
a lot
Why does yeast colonies never allow other bacterial colonies to grow around in any media?
The yeast colonies never allow other bacterial colonies to grow around any media because they don't want competition. The yeast colonies never allow other bacteria colonies to grow around any media because they eliminate competition.
