🔍 Understanding DNA Sequences

DNA sequences are the blueprint for life, containing the instructions for the development and function of all living organisms. DNA is composed of four nucleotide bases - adenine (A), guanine (G), cytosine (C), and thymine (T) - which are arranged in a specific sequence to form genes. Genes are the basic units of heredity, and their sequence and structure determine the characteristics of an organism. The study of DNA sequences has led to a greater understanding of the genetic code and how it is translated into proteins. Genetic Code is a fundamental concept in molecular biology, and its understanding has been facilitated by advancements in Bioinformatics.
