A method of constructing a highly labeled linear polymeric molecule for use in any desired application, and linear polymeric molecules of such structure. The polymeric molecule is a nucleic acid constructed from a large number of one or more types of monomeric oligonucleotide units that are attached together to form an extended strand. Within each polymer, at least one type of monomeric unit is provided which is bound to or designed to bind to a label moiety, providing a polymer with a large number of repeat sequences designed for labeling purposes, resulting in extremely effective signal carrying molecule of considerable versatility.
