Pleаse reаd the pаragraph regarding transcriptiоn terminatiоn and fill in the blanks with wоrds from the word bank below (not all of the words will be used):There are two known mechanisms of transcription termination in prokaryotes. One mechanism requires a protein complex called . This protein complex binds to the , which is located on the RNA that is being transcribed. This protein complex then moves toward the stalled RNA polymerase complex and unwinds the RNA from the DNA. A second mechanism for termination in prokaryotes requires an RNA termination sequence that contains a secondary structure called a followed by a string of nucleotides. Transcription termination for RNA Polymerase II in eukaryotes happens when the termination consensus sequence, , is transcribed leading to cleavage of the mRNA 11-30 nucleotides downstream of the termination sequence. Once cleavage occurs, binds to the 5' end of the mRNA that is still attached to the RNA polymerase/DNA complex and degrades the remaining mRNA. This leads to the dissociation of the RNA polymerase from the DNA.
