A DNA molecule is a polymer, specifically being a type of polymer known as a polynucleotide. In other words, it is made up of many nucleotides. Each nucleotide is made up of three main parts: one or more phosphate (P) groups, a nitrogenous base (adenine, guanine, cytosine, or thymine), and a deoxyribose (pentose, 5-carbon) sugar. Adenine always binds/hydrogen bonds to thymine, and guanine always to cytosine. (According to Chargaff's rules, the amount of pyrimidines is always equal to that of purines.) Hope this helps! :)
DNA is made up of six smaller Molecules--- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine, and guanine).
Our bones support us and allow us to move. Muscles pull on the joints, allowing us to move. Our bones help hold our bodies in place. They need eachtoher. The muscles need the bones for stability.
