What is the purpose of green fluorescent protein ?

Explanation

The green fluorescent protein (GFP ) is a protein containing 238 amino acid residues of 26.9 kDa that exhibits bright green fluorescence when exposed to blue to ultraviolet range (395 nm) .
(ii) GFP refers ot the protein first isolated from the jellyfish Aequorea victoria
Portocol
Green Fluorescnet Protein (GFP)
Isolated from Aequorea victroria (jelly fish )
Gane splicing technique altering the

Introduced into Arabidopsis thaliana plant
`darr `
GFP expressed i A . thaliane plant .
(iii) GFP is an excnllent tool in biology due to its ability to form internal chromophore
without requiring any accessory cofactors ,
without requiring any accessory cofactors gene products , enzymes or substrates other then molecular oxygen .
(iv) In cell and moleculer biology , the GFP gane is frequently used as a reporter of expression . It has benn used in modified formed to make biosensors .
