DNA

Something you can't live without!

DNA

DNA or,Deoxyribonucleic Acid, is the hereditary material in every human body. Almost every cell in the body has the almost the same DNA. DNA is located in the cell's nucleus. DNA is made of chemical building blocks called nucleotides. Nucleotides are made of three parts: a phosphate group, a sugar group, and one of the four nitrogen bases. DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone. DNA contains instructions needed for an organism to develop, survive, and reproduce. DNA does most of the work in our bodies. Heredity is the passing of traits to offspring from its parents. This is the process by which an offspring becomes predisposed to the characteristics of its parent cell, or organism. Replication is the process of making two identical replicas from one original DNA molecule. Protein production is the information that most genes contain to make proteins.

RNA

RNA is a nucleic acid that is present in all living cells. The types of RNA are mRNA, tRNA, and rRNA. RNA's role is to act as a messenger carrying instructions to DNA, for controlling proteins.
