    摘要: A chimera oligonucleotide is provided that can be used in a process for obtaining transcripts and/or amplification of a target sequence of a nucleic acid, having, at its 3' end, a downstream sequence. The oligonucleotide comprises successively, from 5' to 3', 1) a first oligonucleotide segment, of the DNA type, comprising a sense sequence of a promoter of an RNA polymerase, 2) a second oligonucleotide segment, of the DNA type, capable of hybridizing with the downstream sequence, and 3) a third oligonucleotide segment, of the RNA type, capable of hybridizing with a part of the target sequence contiguous to the downstream sequence, the third segment being blocked at 3'. A process using the chimera oligonucleotide and an enzyme system containing DNA polymerase activity, RNA polymerase activity, and a third activity, for example, an RNase H activity provides transcription products of the target. By adding a second chimera oligonucleotide capable of hybridizing with the complement of the target, cyclic amplification of the target and its complement are obtained.
