The function of DNA in a cell is to code the way proteins turn genes on or off. the function of DNA is to make the proteins. DNA is the foundation of life. It's a complex molecule made up of four types of bases, cross connected like a staircase, and twisted into a spiral.
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.
