Genes are made up of DNA. Each chromosome contains many genes. A gene is the basic physical and functional unit of heredity. Genes, which are made up of DNA, act as instructions to make molecules called proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.
Location: DNA is found in the cytoplasm of prokaryotic cells, and chiefly in the nucleus of eukaryotic cells. A small fraction of total DNA is present in mitochondria and chloroplasts. Function: DNA is a long polymer of nucleotides to code for the sequence of amino acid during protein synthesis.DNA is said to carry the genetic âblueprintâ since it contains the instructions or information (called genes) needed to construct cellular components like proteins and RNA molecules.upplement. Structure: Deoxyribonucleic acid (DNA) is composed of two strands that twist together forming a helix. Each strand consists of alternating phosphate (PO4) and pentose sugar (2-deoxyribose), and attached on the sugar is a nitrogenous base, which can be adenine, thymine, guanine, or cytosine.
