Deoxyribonucleic Acid (DNA) Biology Science Facts
DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.
DNA stands for deoxyribonucleic acid.
DNA is a long thin molecule made up of nucleotides.
DNA is like a recipe that holds the instructions for telling our bodies how to develop and function.
Every 3 nucleotide letters form a codon.
