The origin of life continues to remain a matter of debate. The ribonucleic acid (RNA) world hypothesis proposes that 'ribozymes' which store genetic information and possess catalytic functions may ...

Genes contain instructions for making proteins, and a central dogma of biology is that this information flows from DNA to RNA to proteins. But only two percent of the human genome actually encodes ...

Ribonucleic acids (RNAs) are the ultimate cellular insiders. They perform several critical jobs, such as ferrying genetic instructions from a living organism’s DNA to its protein-making machinery (a ...

In recent decades, significant advances in science and technology have greatly enhanced understanding of the many biological molecules that contribute to life’s complexity. RNA is one such molecule ...

Oceans churned with lava. Air filled thick with smoke. Asteroids stormed down incessantly. Life during the Hadean Eon four billion years ago was a struggle, and yet that was when it began. 1,2 With no ...

RIKEN researchers have discovered how an enzyme modifies gene expression by targeting certain stretches of messenger RNA ...

The beginning of life on Earth and its evolution over billions of years continue to intrigue researchers worldwide. The central dogma or the directional flow of genetic information from a deoxyribose ...
