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.
Which organelles inside bacteria make green fluorescent protein?
Organelles inside bacteria do not 'make' GFP. GFP can however be expressed in bacteria by adding the coding sequence for GFP to their genome. This can be done by using a plasmid virus containing the GFP gene sequence. When combined with the plasmid, a very small number of bacteria will take up the plasmid's genome into their own. These bacteria can be isolated by using the 'transform or die' mechanism. Bacteria that do not contain the plasmid are preferentially killed by adding an antibody to the agar. The normal bacteria will not be resistant to this, and will die, but the bacteria which have taken up the plasmid into their genome will also contain an antibody resistance gene. This allows them to live in the presence of the antibody. Since GFP was also added to these bacteria's genome, they will fluoresce.
What is gfp tailswap?
GFP tailswap refers to the swapping of the C-terminal sequence of a GFP (Green Fluorescent Protein) molecule with another protein or peptide sequence of interest. This modification allows the GFP to function as a fusion tag with the added sequence for specific experimental purposes, such as tracking the localization of the target protein in live cells.
What would have happened if we had cut both the jellyfish glo gene and puc18 plasmid with the ecoR1 restriction enzyme?
If both the jellyfish GFP gene and the puc18 plasmid were cut with the EcoRI restriction enzyme, they would produce complementary sticky ends that can anneal together. This allows for the insertion of the GFP gene into the puc18 plasmid, facilitating the creation of a recombinant DNA molecule. This process is essential for cloning the GFP gene, which can then be used for various applications, such as gene expression studies or protein production in host cells. Additionally, transformation of the modified plasmid into a suitable host would enable the expression of the GFP protein.
What is green fluorescence protein?
This is a fluorescent label used in fluorescent miscroscopes. It is a protein that is produced by the bioluminescent jellyfish Aequorea victoria; used to trace the synthesis, location, and movement of proteins of interest in cell biology research. It is used to label live cells; passively difuses across plasma mebrane. It is called Aequorin; it is a Luciferin.Green fluorescent protein (GFP) glows in ultraviolet light.

If we want to now produce a lot of this jellyfish glo protein what do we have to do after this first successful cloning to reach our goal?
In order to produce a lot of jellyfish green fluorescent protein (GFP), you can scale up the production process by increasing the number of clones that express the gene for GFP. This involves optimizing the growth conditions for the clones, such as nutrient availability and temperature, as well as using larger bioreactors to cultivate a higher volume of cells producing GFP. Additionally, you can purify the GFP protein from the cells using techniques like chromatography to isolate and concentrate the protein for further applications.
Can GFP be observed under UV light?
Yes, GFP can be visualized under ultraviolet (UV) light as it naturally emits green fluorescence when exposed to UV light. This property is commonly used in research and imaging studies to track protein expression and localization in living cells.
What is an advantage of using GFP?
One advantage of using Green Fluorescent Protein (GFP) is its ability to visually track proteins and gene expression in living cells and organisms. This non-invasive technique allows researchers to study biological processes in real time without disrupting the system being observed.
Is luciferin and gfp the same thing?
No.

What are the two possible sources of fluorescence within an Ecol colony when exposed to UV light?
The two possible sources of fluorescence within an E. coli colony when exposed to UV light are autofluorescence of the colony itself, caused by endogenous fluorophores present in the cells, and expression of a fluorescent protein, such as green fluorescent protein (GFP), as a result of genetic manipulation.
What is mw of gfp?
Aequorea GFP is a protein of 238 amino acids with a molecular weight of 27 or 30 kDa. Source: http://www.cryst.bbk.ac.uk/PPS2/projects/jonda/intro.htm

What was the experimental method used to determine the GFP three-dimensional structure?
The three-dimensional structure of green fluorescent protein (GFP) was determined using X-ray crystallography. Researchers crystallized GFP and then diffracted X-rays through the crystal to collect data on how the X-rays scattered. By analyzing the resulting diffraction patterns, they could reconstruct the electron density map of the protein, ultimately allowing them to model the three-dimensional structure. This method provided detailed insights into GFP's unique chromophore and its fluorescent properties.
