Fill in the blank about RNA transcription.
The upper DNA strand is the ______ strand and the lower DNA strand is the ______ strand. Promoters upstream of the gene are recognized by _______ in prokaryotes or ______ in eukaryotes. RNA polymerase transcribes RNA in a _____ direction. Termination is the result of the transcription of the RNA sequence signal, ______. Post-(or co-)transcriptional modifications include a 5' ____ and 3' ______ as well as splicing out _______. Spliceosomes consist of "snRNPs".
