Choose the correct option w.r.t the chemical nature of apo-repressor and co-repressor respectively in trp operon.
Protein, Amino acids
Amino acids, Protein
Lipoidal, Sugary
Sugary, Lipoidal
In trp operon, after transcription and translation, an inactive trp repressor protein is formed which is an apo repressor and made up of amino acids. Two molecules of tryptophan join to this aporepressor which is acting as a co-repressor here.
Hence, the correct answer is option 2.
