DNA DNA or deoxyribonucleic acid is where the hertiable genetic information is stored. DNA is a type of nucleic acid and is made up of nucleotides and polymers. Structure: The structure of this double helix DNA is two strands of nucleotide wound around each other. The proper name for this shape is a "double-helix." The outsides are called sugar phosphate backbones. The inside is the four nitrogenous bases. These bases are paired together: Adenine (A) …showed first 75 words of 424 total…

…showed last 75 words of 424 total…pairings between the nucleotides of the two strands of the double helix. Nucleus Structure: Structurally, the nucleus is composed of three main parts, the nucleolus, the nuclear envelope, and the chromatin. The nucleolus contains ribosomes, RNA, DNA, and proteins. Function: The central, spherical structure with a living cell that contains the cell's hereditary material (DNA) and also controls metabolism, growth, and reproduction. Store genes on chromosomes and organizes genes into chromosomes to allow cell division.
