Chemical structure of DNA; hydrogen bonds shown as dotted lines Each end of the double helix has an exposed 5' phosphate on one strand and an exposed 3′ hydroxyl group (—OH) on the other DNA is a long polymer made from repeating units called nucleotides [6][7] The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes [8] In all species

- What are DNA and Genes? - University of Utah
The order of building blocks in a strand of DNA makes up a "sequence " We can read a DNA sequence like letters in a book In fact, we know the sequence of the entire human genome—all 3 billion letters That's enough information to fill roughly 1,000 200-page books! Contained within the 3 billion letters of the human genome are about 21,000 genes Most of our known genes code for proteins
