A gene is structurally, a fundamental unit of hereditary resource or material. The material is uniquely contained in an ordered sequence of nucleotide bases. The sequence thus formed encones a single polypeptide chain. This is inclusive of the regions that proceed and follow the 'coding region' and 'intervening sequences' that lie between individual coding segments. These segments are also referred to as exons. This structure is what accounts for the study of hereditary factors that control our lives.

The term 'cistron' comes from the identification of a gene function via a special test called the 'cis-trans' test. The test determines a section of the DNA that is inclusive of the genetic code for a single polypeptide. It functions as a hereditary unit and is equally accountable for the study of the genetic links that rule our existence.

The gigantic leaps within the spheres of science and technology have enabled detailed study of the complexities within genetic patterns and have in turn, led to a revolution in medicine and research. The study of genes involves the study of the individual units called cistrons and here lies the only difference. The functions and existence of both are interlinked. There is a dedicated stream of research to the study of genes and cistrons and it has brought out some amazing connectivity between generations.

Gene and cistron are the same thing. Genes are located on homologous chromosomes. Their main function is to transmit characters from parents to off springs. These characters can be transmitted after fertilization of egg by sperm. This will produce a fertilized egg or zygote. This will grow in to an individual by and by. This individual will be having some or all of the characters of their parents. Genetic code is accountable for transmission of characters.

It has DNA strands which have nucleotides having codes. Nucleotides have two types: purines and pyrimidines. They have to join with one another by hydrogen bonds. And they have a sugar molecule on one side which is connected to other sugar molecule by the help of phosphorous molecule.
They are with different names but actually they are the same things. One should not get confused due to it. Be careful in studying things from different stuff of books. You may find many names of a single feature but these would be to confuse the reader. These are all the same.
