(i) Chargaff’s Rule of Equivalence: In a double-stranded DNA molecule, the number of adenine (A) residues is equal to the number of thymine (T) residues, and the number of guanine (G) residues is equal to the number of cytosine (C) residues.
(ii) Database: An organized collection of data that can be accessed, managed, and updated.
(iii) Biolistic: A method of gene transfer where DNA is delivered into cells using high-velocity microprojectiles (e.g., gold or tungsten particles).
(iv) Coenzyme: A non-protein molecule that assists an enzyme in its catalytic activity, often by donating or accepting chemical groups.
(v) Optical Activity: The ability of a substance to rotate the plane of polarized light, which is a property of chiral molecules.
