Amino acids can also be basic, like lysine, or acidic, like glutamic acid. The sequence and interactions between the side chains of these different amino acids allow each protein to fold into a ...
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 ...
Molecules friendly to life have been found in samples of the asteroid Bennu, which NASA collected with a robotic probe five ...

Samples contain all five nucleobases of DNA and RNA, supporting theory that asteroids may have seeded Earth with life's ...
Bennu’s parent asteroid, which formed around 4.5 billion years ago, seems to have been home to pockets of liquid water.
(Hint: It’s a lot.) A biggie as of late? Amino acids, which are the building blocks of protein. The 11 amino acids our bodies synthesize are called “nonessential,” but we need nine others (k ...
Samples from the asteroid Bennu contain the building blocks of life as we know it. Scientists are enthusiastic.
