<P> pGLO is made up of three genes that are joined together using recombinant DNA technology . They are as follows: </P> <Ul> <Li> Bla, which codes for the enzyme beta - lactamase giving the transformed bacteria resistance to the beta - lactam family of antibiotics (such as of the penicillin family) </Li> <Li> araC, a promoter region that regulates the expression of GFP (specifically, the GFP gene will be expressed only in the presence of arabinose) </Li> <Li> GFP, the green fluorescent protein, which gives a green glow if cells produce this type of protein </Li> </Ul> <Li> Bla, which codes for the enzyme beta - lactamase giving the transformed bacteria resistance to the beta - lactam family of antibiotics (such as of the penicillin family) </Li> <Li> araC, a promoter region that regulates the expression of GFP (specifically, the GFP gene will be expressed only in the presence of arabinose) </Li>

Explain the relationship between the sugar arabinose and the production of green color
