Marking 

(biology), the tagging of a group of cells, individual cells, or intracellular structures to study what happens to them subsequently. Marking is used in research on developmental biology, chiefly in embryology. Methods used for marking are in vivo dyeing, ³H-thymidine tagging, and genetic and biochemical markers (transplantation of cells or groups of cells into the embryos of animals of different species, into normal and mutant individuals, or into individuals with different ploidies).

any of several ways of identifying products or parts with letters, numbers, inscriptions, notices, or conventional signs (symbols) on labels, packing, sealing, or the product itself. There is also transport marking, which usually contains the address of the sender (consigner) and recipient (consignee) of the freight, as well as the notices and/or symbols (signs) specifying the freight-handling methods during transport and during loading and unloading.
