Answer 1

Ans-3 Both zink finger and helisi - turn-Helle region are DNA binding protein. That are bind non-covalentally so these are Interaction between the these protein and DNA option - I is correct zinc finger are bind the usully tetramer sometime bind reexameric form with two ana Ans- 4 Trp operon system are found in Prokaryotic (Bacteria ) cell. Tap are negative controlled by the top. amino ands are present then these are inhibited top are are both processes are occure Ist it transcribed then it translated in the controlling of leade sequence. so option v are correct means All of the above.
