HOW DOES DNA MAKES US UNIQUE?Each organism's DNA is unique, all DNA is composed of the same nitrogen-based molecules. It is simply the order in which these smaller molecules are arranged that differs among individuals.

Nitrogenous Bases in DNA:The four nitrogen bases found in DNA are adenine, cytosine, guanine, and thymine. Each of these bases are often abbreviated a single letter: A (adenine), C (cytosine), G (guanine), T (thymine). The bases come in two categories: thymine and cytosine are pyrimidines, while adenine and guanine are purines.

CHROMOSOMESEach chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

BASE PAIRSThe base pairs of DNA are adenine with thymine (A & T) and cytosine and guanine (C & G).

They also assist with the formation of new molecules by reading the genetic information stored in DNA. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs.
