Explain why DNA is a better genetic material than RNA.

Explanation

DNA is a better genetic material. Because,
1) It has ability to generate its replica
2) DNA is chemically less reactive and structurally more stable when compared to RNA.
3) Presence of thymine in the place of uracil confers additional stability of DNA.
4) Two strands being complementary if separated by heating come together, when appropriate condition is provided.
5) Stability as one of the properties of genetic material was very evident in Griffith.s "transforming principle" itself. That heat, which killed the bacteria at least did not destroy some of the properties of genetic material.
