Why is DNA a better genetic material not RNA?
Answers
Explanation:
With the exception of certain viruses, DNA rather than RNA carries the hereditary genetic code in all biological life on Earth. DNA is both more resilient and more easily repaired than RNA. As a result, DNA serves as a more stable carrier of the genetic information that is essential to survival and reproduction.

Explanation:
One single thing that was fundamentally essential for origin of life was a molecule that could replicate itself or could reproduce. DNA and RNA are polynucleotides and are known to possess this essential property. It was due to the presence of complementary base pairing.
DNA and RNA are composed of 4 building blocks known as nucleotides. DNA is composed of Adenine; Guanine; Cytosine and Thymine whereas RNA is composed of Adenine; Guanine; Cytosine and Uracil. While replication of a DNA or RNA template complementary bases form opposite template to the original one (A pairs with T and C with G)
Genetic material (RNA or DNA) of an organism carries information of the structure, shape and function of each and every cell of that organism, and carries the same information for generations. Hence the more stable the genetic material, the less are chances in incorporation of mutations in genome. With evolution the lesser stable genetic material (RNA) got replaced by the more stable ones (DNA).
RNA is unstable because of the presence of Uracil instead of Thymine. RNA has ribose sugar and DNA has deoxy-ribose sugar in their monomers, the presence
