Genes are specific fragments of DNA, which ache a particular structure, including an initiation send from which expression of the gene starts and a stop point. In among, there are blocks DNA which code for the protein called exons, often separated by blocks of non-coding sequenc e called introns, which are removed before t! he protein is made. In between each gene there is lots of non-coding DNA.
