A gene is a segment of DNA (on a chromosome) which encodes for a gene product. A gene product can be a protein or an RNA molecule (such as a rRNA or a tRNA). In order to understand this, we have to know the basic structure of DNA. DNA is the nucleic acid macromolecule that makes up chromosomes. DNA is made up of only four separate pieces of information called nitrogen-containing bases. In summary, the specific "bases" which make up part of the nucleotide structure, are abbreviated by letters: G, C, A, and T. It is ...
