Nucleic acid and rna world
Since its inception in 1962, the nucleic acids gordon conference has been a premier venue for the dissemination of exciting and transformative discoveries concerning the structure and function of dna and rna and the complex mechanisms underlying dna/rna synthesis, processing, modification, and repair and the regulation of nucleic acid transactions at all stages of gene expression. Rna (ribonucleic acid) is similar to dna in that both are composed of long chains of nucleotides however, rna is a single strand and therefore much smaller than dna although dna contains the genetic information that determines all cell characteristics and functions, rna stores and transfers the genetic code contained in the dna. Their peptide-rna hypothesis contradicts the widely-held rna-world hypothesis, which states that life originated from nucleic acids and only later evolved to include proteins. Nucleic acid medicine next generation drugs using dna and rna with research conducted in countries around the world nucleic acid medicines are next generation drugs which use “nucleic acids” such as dna and rna.

Nucleic acid is an important class of macromolecules found in all cells and viruses the functions of nucleic acids have to do with the storage and expression of genetic information. Nucleic acids (dna, rna) are large polymers, made out of monomer building blocks called nucleotides the nucleotides have a similar structure with three 'subunits': a phosphate group a sugar group : deoxyribose in dna and ribose in rna a nitrogenous base : adenine, cytosine, guanine, thymine or uracil. Early life may have emerged from a mixture of rna and dna building blocks, developing the two nucleic acids simultaneously instead of evolving dna from rna according to the rna world hypothesis, early life used rna to carry genetic information and perform biochemical catalytic reactions.
