WebApr 1, 2024 · The CISS effect implies that the electron transmission probability through a chiral molecule, in which the spin and chirality are favorably matched, will be larger than that through an achiral molecule. As an electron transits, a chiral molecule spin couples with its linear momentum, and this coupling reduces the probability for backscattering ... WebAmino acids are built by protein biosynthesis, which involves the activation of amino acids followed by their addition to a growing polypeptide chain. During activation, an amino acid is linked to a transfer RNA (tRNA) molecule specific to that amino acid, forming an aminoacyl-tRNA. Explanation: Amino acids are the building blocks of proteins ...
