RNA that nearly self-replicates offers new clues to life’s origins
A strand of RNA just 45 nucleotides long can copy its own complementary sequence in frozen conditions that may resemble early ...
Antisense oligonucleotides (ASO) hold great promise for pharmacotherapy. Now, researchers at Tokyo Medical and Dental University (TMDU) and Ionis Pharmaceuticals, advancing their earlier work on a ...
Even those who doubt the RNA World hypothesis may be hard-pressed to argue against it. Consider the predicament faced by a team of scientists at Scripps Research. They suspected that RNA was a poor ...
Researchers from Tokyo Medical and Dental University (TMDU) and Ionis Pharmaceuticals, USA, report a modification wherein replacing the RNA strand of a heteroduplex oligonucleotide with DNA may ...
RNA, or ribonucleic acid, is a essential biological molecule that plays a crucial role in various cellular processes. It is a polymeric molecule composed of nucleotides, each containing a ribose sugar ...

This RNA almost self-replicates, which could explain life's origins
(Christoph Burgstedt/iStock/Getty Images Plus) The RNA world hypothesis posits that molecules made up of ribonucleic acids (RNA) are responsible for kickstarting evolution and all life on Earth – and ...
Every living cell transcribes DNA into RNA. This process begins when an enzyme called RNA polymerase (RNAP) clamps onto DNA. Within a few hundred milliseconds, the DNA double helix unwinds to form a ...
Researchers have devised a molecular structural modification that boosts the efficacy of antisense oligonucleotide-based drugs by replacing the RNA strand of a heteroduplex oligonucleotide with DNA.
