For years, researchers described DNA and RNA as linear chains of four building blocks—the nucleotides A, G, C, and T for DNA; and A, G, C, and U for RNA. But these information molecules are much more ...

NASA scientists found amino acids, key minerals, and nucleobases for DNA in samples from the OSIRIS-REx asteroid mission. It's a win for alien life.

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

In the late nineteenth century, a German biochemist found the nucleic acids, long-chain polymers of nucleotides ... giving two forms: RNA and DNA. In 1943, American Oswald Avery proved that ...

Synthetic biologists from Yale were able to re-write the genetic code of an organism—a novel genomically recoded organism ...

Sunburn has traditionally been attributed to UV-induced DNA damage, but it turns out that this is not the full truth.

RNA is more subject to degradation than DNA, whether chemical, physical ... It also incorporates dUTP nucleotides during second-strand synthesis, allowing scientists to trace amplified sequences back ...

This type of chart displays all the possible codons — essential components of DNA and RNA molecules ... the four possible ...

These nucleotides can then be further processed to form the pyrimidine bases found in DNA and RNA. The pyrimidine biosynthetic pathway is tightly regulated to ensure the proper balance of nucleotides ...
