Answer:
Option (a), (c), and (d).
Explanation:
The DNA is the genetic material of almost all the living organisms but in case of some viruses RNA acts as the genetic material. The DNA requires the binding of proteins and factors for the proper functioning of the cellular system.
The DNA and protein interaction is bounded by non covalent interactions as these interactions are not permanent in nature. The non covalent interaction include the hydrogen bonding, vander walls and ionic interaction. The covalent interaction is the strongest interaction present in nature.
Thus, the correct answer is option (f).
