The present invention provides a method for amplifying a nucleic acid molecule. The method involves mixing an RNA template with a composition having a reverse transcriptase, a DNA polymerase and a RT inhibition reducer. The RT inhibition reducer can be Sso7d, Sac7d, Sac7e, Sso7e, AluI methylase, suramin, a phosphorothioate oligodeoxycytosine, a phosphorothioate oligodeoxyadenine, a phosphorothioate oligodeoxythymine or poly(rA)(dT). The mixing forms a mixture that is incubated under conditions sufficient to synthesize a DNA molecule complementary to all or a portion of the RNA template, thereby amplifying the nucleic acid molecule.
