There are 20 standard amino acids that are commonly found in proteins. These amino acids can be classified based on various criteria, such as their essentiality, polarity, and side chain properties.

Some of these may have relied on non-standard amino acids, possibly formed in environments like alkaline hydrothermal vents, which are thought to be key to life's origins.

Hidden within the genetic code lies the "triplet code," a series of three nucleotides that determine a single amino acid. How did scientists discover and unlock this amino acid code? Once the ...

Scientists discovered numerous organic compounds in samples from the asteroid Bennu, including key amino acids, DNA, and RNA.

Two science teams pored over samples from the B-type asteroid Bennu, finding chemicals linked to the beginnings of life and ...
