A composition for hot-start reverse transcription reaction and a composition for reverse transcription PCR are disclosed. The composition is obtained by adding pyrophosphate and pyrophosphatase to an aqueous solution containing reaction buffer solution, MgCl, four kinds of dNTPs, and reverse transcription polymerase in a single reaction tube. The composition for hot-start reverse transcription reaction is obtained by freezing or drying the composition. The composition show increased stability and long-term storage stability. Also, disclosed is a composition that additionally includes DNA polymerase, and, thus, enables a hot-start reverse transcription reaction and a PCR reaction to be sequentially performed. A method for amplifying a nucleic acid by using the composition. The composition of the invention can be conveniently and effectively used in multiplex reverse transcription PCRs or real-time quantitative reverse transcription PCR.
