What else can I help you with?
Which insect uses the chemical luciferin for display purposes?
Firefly luciferin is the luciferin found in many Lampyridae species. Latia luciferin is from freshwater snail. Vargulin is found in certain ostracods and deep sea fish.
What is luciferin in fireflies?
Luciferin is a compound that gives the fireflies, and any organism that has it, its light.
Which Luciferin is broken down in cells controlled by?
an enzyme
What is luciferin controlled by?
Luciferin is controlled by enzymes called luciferases. These enzymes catalyze the oxidation of luciferin to produce light in bioluminescent organisms. The reaction requires other cofactors such as oxygen and ATP.
Is luciferin an element?
No. It is a compound.
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 chemical is in a firefly's body to help it produce light?
This chemical is luciferin.
What chemical is in a firefly when they produce light?
The chemical is called luciferin. Fireflies possess an enzyme called luciferase that interacts with luciferin to produce light through a reaction called bioluminescence.
Luciferin is a molecule that when broken down in fireflies produces heat and light. The rate at which luciferin is broken down in cells is controlled by?
the enzyme luciferase. Luciferase catalyzes the oxidation of luciferin, resulting in the release of light. The rate of luciferin breakdown and light production can be regulated by factors such as temperature, pH, and the availability of cofactors.
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.
What three substances are needed for bioluminescence to occur?
Luciferin, and enzyme called luciferase. Bioluminescence does not occur in the absence of oxygen.
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
