How did viruses evolve? Are they a streamlined form ... agree that the very first replicating molecules consisted of RNA, not DNA. We also know that some RNA molecules, ribozymes, exhibit ...

RNA viruses -- including coronaviruses -- have genetic material consisting of a single ribonucleic acid (RNA) strand, as opposed to double-stranded DNA in DNA viruses, like Herpes viruses.

A study reveals DNA and RNA epigenetics work together as a complementary system for precise gene regulation, crucial for cell ...

(A base is a pair of compounds that are the building blocks of RNA and DNA.) Because the genome is so large, many mutations could occur during replication that would cripple the virus, but SARS ...

NASA scientists found amino acids, key minerals, and nucleobases for DNA in samples from the OSIRIS-REx asteroid mission.

The US just recorded the first death from severe bird flu. Experts say it's not too early, or unreasonable, to prepare for the worst.

Sunburn has traditionally been attributed to UV-induced DNA damage. However, a new study reveals that RNA, another vital cellular molecule, plays a major role in triggering acute sunburn reactions.

US mosquito species exhibit minimal competence for transmitting Oropouche virus (OROV), with low infection and transmission ...

In this review of RNA therapies, we paint an overview of what’s going on in a field that is addressing a number of diseases.
