Interpretation:
On the basis of the structure, determine whether the given molecule is a
Concept introduction:
Our body produces a number of proteins.
The amino acids in the proteins are coded by
Nucleic acids are
Each nucleotide is made up of base, sugar, and phosphate group.
The nucleotides differ in their base unit, which can either be adenine (A), guanine (G), cytosine (C), uracil (U) and thymine (T).
In DNA, the four bases are adenine (A), guanine (G), cytosine (C), and thymine (T).
In RNA uracil replaces thymine, the four bases are adenine (A), guanine (G), cytosine (C), and uracil (U).
The structure of nitrogenous bases is given as below:
