Concept explainers
a.
To identify:
The guanine as a purine or a pyrimidine and name it.
Introduction:
The organic compound having a “nitrogen” atom having chemical characteristics of bases is known as “nitrogen base”. A nitrogenous base connects the two
b.
To identify:
The cytosine as a purine or a pyrimidine and name it.
Introduction:
The organic compound having a “nitrogen” atom having chemical characteristics of bases is known as “nitrogen base”. A nitrogenous base connects the two nucleic acids. It resembles the base due to the availability of a “lone pair” of electrons on the nitrogen. There are two types of nitrogenous bases “purines” and “pyrimidines”.
