DNA is said to be the hereditary material carrier of any living being. DNA stands for deoxyribonucleic acid and is nearly the same in every cell of the human body. It’s one of the greatest abilities is to replicate and form the new strands which are complementary to the parent DNA strand or the template DNA. The location of the DNA is always determined to be in the nucleus but some small amount is also present in the mitochondria and in plants, it’s also present in the chloroplast. The mitochondria are the cell organelle that is responsible for the energy production in the cell whereas, the chloroplast is the cell organelle in plants which are responsible for the pigmentation of the plant leaves in turn involved in photosynthesis. DNA is the prime source of a biological molecule that is involved in forming living beings. And this phenomenon occurs through cell division in which one cell divides to produce two daughter cells that consist of the required genetic information. One of the well-recognized activities followed by the DNA is “DNA Replication” which is the process of the one DNA strand forming duplicate of the other DNA strand is necessary for the keeping the integrity of the DNA molecule.
