Butola V, Revathi B, Anila G and Kumar S

DNA (Deoxyribonucleic acid) is also known as the basic unit of nucleus which is present inside the cell. DNA is a molecule which makes each and every individual unique. It contains the information that how an organism needs to develop, live and reproduce. DNA is the medium by which genetic material is passed down from parents to their offspring so basically DNA is the hereditary material in almost all the organisms. Every cell in our body has the same DNA. Deoxyribonucleic acid as the name suggests its structure it is made up of deoxyribose sugar. DNA molecule is consisting of two polynucleotide chains contains four different types of nucleotide subunit these chains of DNA is known as DNA strands. Between the nucleotide hydrogen bond holds the structure in each type of nucleotide subunit only base differs from each other.
