The process differs for each of the three RNA polymerases.

RNA polymerase is free to continue transcribing the entire operon.

These viruses fall into four groups based on the RNA polymerase gene.

RNA polymerase can be isolated in the following ways:

RNA polymerase then can transcribe the message (expressing the gene).

These proposals were based on an analysis of the RNA polymerases and are still under consideration.

As noted above, RNA polymerase makes contacts with the promoter region.

The other lineage formed all of the modern cellular RNA polymerases.

Late genes are now transcribed by the host's RNA polymerase.

Thus, RNA polymerase activity apparently has been independently "invented" on several occasions.

The situation is transformed by the use of the RNA polymerase chain reaction (fig 2).

The natural target of the toxin is chloroplast RNA polymerase.

RNA polymerase can then begin to transcribe operon genes.

The discriminating factor between the three promoters appears to be the same for each RNA polymerase.

The virally encoded RNA polymerase is also found in the interior.

RNA polymerase is able to bind to core promoters in the presence of various specific transcription factors.

When the sigma factor and RNA polymerase combine, they form a holoenzyme.

After the first bond is synthesized, the RNA polymerase must clear the promoter.

It is facilitated by RNA polymerase and transcription factors.

Sigma factors play critical roles in the recognition of promoters by RNA polymerase.

The promoter is recognized by RNA polymerase, which then initiates transcription.

During the promoter escape transition, RNA polymerase is considered a "stressed intermediate."

The history of the discovery of the archaeal RNA polymerase is quite recent.

Initiation; requiring construction of the RNA polymerase complex on the gene's promoter.

Eukaryotic RNA polymerase does not directly recognize the core promoter sequences.

In humans cells, SIRT7 has only been shown to interact with two other molecules: RNA polymerase I (RNA Pol I) and upstream binding factor (UBF).

These include the Xenopus protein importin and its yeast homolog, SRP1 (a suppressor of certain temperature-sensitive mutations of RNA polymerase I in Saccharomyces cerevisiae), which bind to the NLS.
