DNA, Chromosomes and Genes
DNA, chromosomes, and genes constitute the fundamental building blocks of life, orchestrating the intricate dance of heredity and biological diversity. These molecular entities, nestled within the nucleus of every living cell, encode the blueprint of an organism's traits and characteristics. DNA, the double-helix molecule, serves as the repository of genetic information, while chromosomes act as the condensed structures that organize and package this vital material. Genes, nestled along the length of chromosomes, dictate the expression of specific traits, guiding the intricate interplay of inheritance and evolution. Together, DNA, chromosomes, and genes form the cornerstone of modern genetics and biological inquiry.
