DNA or Deoxyribonucleic acid is the hereditary material in humans. Basically, DNA bases pair up with each other, and each base is also attached to a sugar molecule and a phosphate molecule. As we know that the Deoxyribonucleic acid (DNA) is essential to almost all lives presented on the earth. In London, scientists have demonstrated that DNA may caused the life. It is a common fact that life begins with DNA, but most scientists are of the view that life may have started with RNA the Ribonucleic acid, and it stores the genetic information. The Prebiotic experts have did not focus on DNA, as it cannot possibly form spontaneously. Most of the scientists think life based on RNA gradually turned into DNA and its reason is that DNA can perform the storing function in a far better way than RNA. It is also a fact that RNA is responsible in making the first DNA.
It has also been seen that according to chemists the building blocks of DNA can form spontaneously from chemicals thought to be present on the primordial Earth. They also said that RNA can be generated easily by using chemicals that probably existed on the early Earth.
Many chemists have largely ignored DNA nucleotides, because of the suggestion of the complexity. The scientists reported that DNA cannot possibly form spontaneously. They have switched the RNA life to DNA. RNA can speed up the chemical reactions just like as protein. RNA structure can also turn into complex new shape and it has the tendency to clamp on other molecular substances. It has also been tested that RNA synthesis is far more easier in the human body. Recently, the researchers have successfully synthesized the generation of RNA, that is supposedly in though to be existed initially on earth existance. In a nutshell, anyone can say that DNA may have predated the origin of life itself.
