摘要：

The T7 RNA polymerase-dependent transcription was studied as a function of nucleotide sequence structures positioned upstream of the T7 promoter. Model double-stranded DNA templates were constructed for this purpose. They contained a target sequence of 485 base pairs (cDNA fragment of Venesuelian encephalomyelitis equine virus genome), T7 promoter consensus and different extra base sequences upstream of the T7 promoter. The level of the target sequence transcription was clearly determined by the extra base sequence. The presence of one extra base pair G . C ensured the most pronounced effect, transcription was increased one order of magnitude in comparison with template which has only a canonical T7 promoter sequence at the 5'-end.
