New Study Brings Scientists Closer to the Origin of RNA

(Phys.org) —One of the biggest questions in science is how life arose from the chemical soup that existed on early Earth. One theory is that RNA, a close relative of DNA, was the first genetic molecule to arise around 4 ...

The origin of life: A paradigm shift

According to a new concept by LMU chemists led by Thomas Carell, it was a novel molecular species composed out of RNA and peptides that set in motion the evolution of life into more complex forms.

How RNA formed at the origins of life

A single process for how a group of molecules called nucleotides were made on the early Earth, before life began, has been suggested by a UCL-led team of researchers.

Scientists discover dual-function messenger RNA

For the very first time, a study led by Julian Chen and his group in Arizona State University's School of Molecular Sciences and the Biodesign Institute's Center for the Mechanism of Evolution, has discovered an unprecedented ...

New study identifies possible ancestors of RNA

Researchers from the Georgia Institute of Technology may have made headway in helping determine the origin of life by identifying three different molecules that self-assemble to form a molecular structure with features characteristic ...

Researchers discover new mechanism of DNA repair

The DNA molecule is chemically unstable giving rise to DNA lesions of different nature. That is why DNA damage detection, signaling and repair, collectively known as the DNA damage response, are needed.
