____RNA polymerase plus sigma factor together are called ______ Core; holoenzyme
A consensus sequence of any genetic element is the sequence with the most likely base/bases at each position.
DNA-dependent____ polymerase makes a copy of DNA that is then used for translation. The process carried out by this enzyme is called______. RNA; transcription
A consensus sequence of any genetic element is the sequence with the most likely base (or bases) at each position
Molecules of sRNA do not encode proteins but are used to____ the stability or translation of specific mRNAs into proteins. regulate
In the absence of Rho, what can bring about transcription termination? GC-rich region near the 3' terminus followed by four to eight uridines

Different _____ can bind simultaneously to the start of each gene within a polygenic mRNA. ribosomes
What is a codon? A set of three nucleotides that encodes a particular amino acid
What is sigma factors? A protein needed to bind RNA polymerase for the initiation of transcription in bacteria. No sigma factors, no transcription.
