DNA or deoxyribonucleic acid is a long molecule that contains our unique genetic code. Like a recipe book it holds the instructions for making all the proteins in our bodies. DNA replication is the process by which DNA makes a copy of itself during cell division.
What DNA Does. Â­DNA carrÂ­ies all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein.In DNA, each protein is encoded by a gene (a specific sequence of DNA nucleotides that specify how a single protein is to be made).he particular sequence of amino acids in the chain is what makes one protein different from another. This sequence is encoded in the DNA where one gene encodes for one protein. The genetic code consists of 3-base words or codons that specify particular amino acids.
