Deoxyribonucleic acid, commonly known as DNA, serves as the fundamental building block of life. This remarkable molecule contains the genetic instructions that dictate the development, functioning, and reproduction of all living organisms. In this article, we will explore the fascinating world of DNA, its structure, functions, and significance in various aspects of science and everyday life.

The Structure of DNA:

DNA is composed of two long strands that coil around each other to form a double helix. Each strand consists of repeating units called nucleotides, which are made up of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G). The structure of DNA is often like
