44 . A method of synthesizing one or more nucleic acid molecules comprising incubating one or more nucleic acid templates with 2 or more modified nucleotides under conditions sufficient to make one or more first nucleic acid molecules complementary to all or a portion of said one or more templates, wherein at least one said nucleic acid molecule contains said 2 or more modified nucleotides incorporated therein.
45 . A method of claim 44 , wherein at least one of said modified nucleotides is selected from the group consisting of aminoallyl-dUTP and aminohexyl-dATP.
46 . A method of claim 44 , wherein at least two of said modified nucleotides is selected from the group consisting of aminoallyl-dUTP and aminohexyl-dATP.
47 . A method of claim 44 , wherein said nucleic acid template is mRNA or a population of mRNA molecules.
48 . A method of claim 44 , further comprising incubating said one or more nucleic acid molecules under conditions sufficient to make one or more second nucleic acid molecules complementary to all or a portion of said one or more first nucleic acid molecules.
49 . A method of claim 44 , further comprising incubating said one or more nucleic acid molecules in the presence of one or more detectable labels under conditions sufficient to couple one or more of said labels to at least one of said modified nucleotides incorporated therein.
50 . A method of claim 49 , wherein at least one of said labels is a fluorescent label.
