The chemical element sulfur is essential for all lifeforms and is a building block of proteins and amino acids. By studying ...

Each protein is a molecule made up of different combinations of 20 types of smaller, simpler amino acids. Protein molecules are long chains of amino acids that are folded into a three-dimensional ...

A peptide bond is a covalent bond that forms between the carboxyl group of one amino acid and the amino group of another, with the release of a water molecule. This process, known as condensation or ...

How did scientists discover and unlock this amino acid code? Once the budding molecular biology community was convinced about the triplet code, the race to decode which triplets specified which ...

In its structure, DNA contains a pattern for producing amino acids, proteins, lipids, sugars, and every other biomolecule an organism makes. The parts of a DNA molecule that have these ...

There are 20 amino acids that make up proteins and all have the same basic structure, differing only in the R-group or side chain they have. Amino acids are in an equilibrium between two acids with ...

Each tRNA molecule has an anticodon that is complementary to a specific codon on the mRNA. The tRNA binds to its corresponding amino acid and transports it to the ribosome, where it is incorporated ...
