This continuous process takes place in all living organisms, and as such, ensures biological inheritance. DNA relates to the genes and chromosomes in such as way that it holds all the information in chromosomes necessary in encoding genes. Chromosomes appear in cells and contain genetic information usually passed down through a given lineage. A gene is a DNA sequence that determines particular traits in these living organisms.
