(a)
Interpretation: The reason corresponding to the fact that the two purine bases (
Concept introduction: The building block of DNA and RNA is
(b)
Interpretation: The reason corresponding to the fact that the hydrogen bonding between guanine and cytosine is more favorable than hydrogen bonding between guanine and thymine is to be stated.
Concept introduction: The building block of DNA and RNA is nucleotide. It is an organic molecule. There is a specific structure for each and every nucleotide which enables the formation of DNA and RNA. DNA is composed by the four nitrogenous bases. These are connected by the chemical bond.
