DNA’S Dynamic Nature Makes It The Blueprint For Life, New Study Finds

Once considered the most essential building block of life, the RNA was replaced by DNA as the main repository of genetic information. A new study published Monday attempts to explain why that happened.

The dynamic nature of the DNA double helix that maintains the stability of the genome forms the basis of the research. The double helix consists of two long strands with four chemical building blocks, called bases, each containing rings of carbon along with configurations of nitrogen, oxygen, and hydrogen, making up the steps that join the two strands of the double helix.
