Energy-dependent hydrogen bonds in supercoiled DNA
Chirality Check Most biological macromolecules are homochiral, and enzymes help to maintain this state of affairs; for example, checkpoints ensure that only l-amino acids are incorporated into proteins during translation. The fixation of the only achiral amino acid, glycine in position 6 of the gonadotropin releasing hormone decapeptide protein links the nutrient energy-dependent pheromone-controlled physiology … Energy-dependent hydrogen bonds in supercoiled DNA
