What is DNA and how it is important for life?
In all living things, DNA is essential for inheritance, coding for proteins, and providing instructions for life and its processes. DNA dictates how a human or animal develops and reproduces, and eventually dies. Human cells normally contain 23 pairs of chromosomes, for a total of 46 chromosomes in each cell.
What is DNA explain?
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person's body has the same DNA. ... DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule.
What is the importance of DNA essay?
DNA plays important role in various ways. It is used in transcription i.e. synthesis of mRNA which in turn is used in protein synthesis. It carries genetic information from one generation to the next generation. DNA stores and transmits the genetic information in cells.
Why is DNA such an important?
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
