Question

1. If you have an operon containing genes that code for proteins that will aid the cell in getting rid of an antibiotic, what type of operon is it?

Answer 1

Ans: operon is inducible operon.

explanation:- operon is gene which regulate protein synthesis in bacteria and virus. there are two types of operon inducible and repressible operon. inducible operon induce synthesis of mRNA and protein which helps in catalytic activity. lac operon is an example of inducible operon as it synthesize protein (enzyme) that metabolize lactose. in above example operon contains gene which code for protein (enzyme) that helps in getting rid of antibiotics hence it is inducible operon. Trp operon is an example of repressor operon. it synthesize enzyme which helps in synthesis of amino acid tryptophan. so when tryptophan level is low it express gene for enzyme and it repress when tryptophan level is high.
