DNA
DNA (DeoxyriboNucleic Acid) is the blueprint of life. DNA is a hereditary material in humans and contains genetic information passed down from generations. In DNA replication, when the two daughter strands are formed, both of them are accompanied by a parent strand, this process is called semi-conservative replication. DNA is what determines the individuality of a person and their distinct appearance. It belongs to the class of molecules called nucleic acids, which consist of many nucleotides linked in a long chain. After the process is completed two new daughter strands are created.
