Document Summary
Characteristics of rna polymerase: an rna polymerase performs a template di(cid:396)e(cid:272)ted s(cid:455)(cid:374)thesis i(cid:374) the 5" to 3" di(cid:396)e(cid:272)tio(cid:374). But unlike dna polymerases, rna polymerases do not require a primer to begin transcription. Genes that code for most of the large rna molecules (rrnas) found in ribosomes. Protein coding genes (produce mrnas); also, genes that code for rnas that function in ribosome assembly and in processing and regulation of mrnas. Genes that code for transfer rnas (trnas), for one of the small rrnas found in ribosomes, and for noncoding rnas; also, genes that code for rnas that function in ribosome assembly and in processing and regulation of mrnas. Vise versa for upstream: the place where transcription starts is said to be called the 1+ site. In the same promoters, a sequence of another 6 bases was found (ttgaca) but was found about.
