Explanation:
The Ribonucleic acid can be defined as the genetic material of some virus. They contains ribose sugar, nitrogenous bases and phosphate group.
The nitrogenous bases are attached complementary to each other. The Adenine is attached to thiamine( uracil in case of RNA) by double hydrogen bonds.
The guanine and cytosine are attached to each other by triple hydrogen bonds.
