DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
DNA is a long molecule made up of twisted strands of the bases A, T, C and G. Genes are sections of the DNA and each gene has the code for creating a specific protein. The sequence of bases in the gene controls which amino acids are created and joined to make a specific new protein or enzyme molecule.very time the same sequence of three bases occurs in the DNA molecule, the same amino acid is added to make up the protein. There are four different bases in DNA (A, T, C and G). Page: 1  1. 2  2. 3  3. 4  4. 5  5. 6  6.
