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)

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.
