Cinderella Castle was completed in July 1971, after about 18 months of construction. The castle is 183 feet (56 m) tall, as measured from water-level. Many sources quote the height as six feet taller, but that is measured from the concrete bottom of the moat, which itself is 6 feet (1.8 m) deep at the bridge.
In biochemistry, a binding site is a region on a protein or piece of DNA or RNA to which ligands (specific molecules and/or ions) may form a chemical bond. An equilibrium exists between unbound ligands and bound ligands.hen a binding site of one protein identifies with another protein's surface, a non-covalent bond is formed between the two polypeptide (peptide) chains and a combined new protein is formed. A more specific type of binding site is the transcription factor binding site present on DNA.
In biology, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction. The active site consists of residues that form temporary bonds with the substrate and residues that catalyse a reaction of that substrate. The active site is usually a groove or pocket of the enzyme which can be located in a deep tunnel within the enzyme, or between the interfaces of multimeric enzymes. An active site can catalyse a reaction repeatedly as its residues are not al
