DNA could be considered the building block of life, DNA is basically chains of nucleotides which are built on sugar and phosphate and wrapped around each other to form the double helix. It supports guanine, cytosine, adenine, and thymine. Guanine and cytosine are always across from each other on the helix so are adenine and thymine. This is very important for the reproduction of genetic material because it allows the strands to divide and copy themselves it can do this because it only needs half of the material in the helix to duplicate its self.DNA, also known as deoxyribonucleic acid, has the hereditary substance which is needed for all those living creatures to survive, develop, as well as work (National Institutes of Health, 2011). The cells in an organism’s system have got DNA, and the DNA is usually the same in every individual cell regardless of any other consideration (National Institutes of Health, 2011). The vast majority of DNA is located in the cell nucleus; however a lesser amount is located in the mitochondria. In cases like this, it is generally known as mitochondrial DNA (National Institutes of Health, 2011).Chromosomes are actually very small structures which are situated in every cell, and they have DNA as well as genes (Sydney Genetics, 2008). Human beings, for instance, have got forty six chromosomes; all men have got a single pair of X-Y sex chromosomes whereas all women have got a single pair of X-X sex chromosomes. The rest of the forty four chromosomes are referred to as autosomes, and they are generally non-sex chromosomes. They do not play any major part in an individual’s personality (Sydney Genetics, 2008). Genes are the genetic substance found in the chromosomes. Genes are passed on from the living organism’s parents to the children, and they decide factors for example the offspring’s physical qualities, attitude, and the way that child reacts to its atmosphere (Nordqvist, 2009). Genes are regarded as the fundamental unit of heredity and are needed for all living things to survive (Nordqvist, 2009).DNA, chromosomes, as well as genes are similar in that they have got a living organism’s genetic information. These are the parts which make up each specific qualities of an existing organism. DNA, chromosomes, and genes vary in that the chromosomes have the living organism’s DNA, as well as the DNA is arranged into specific parts generally known as genes.
