Published	08/28/2024	What type of RNA does RNA polymerase III transcribe?
Published	08/28/2024	Transcription is regulated by multiple {{c1::enhancers}} located {{c2::away}} from the promoter
Published	08/28/2024	{{c1::TATA-box-binding protein}} binds the TATA box
Published	08/28/2024	{{c1::TAF2}} binds the initiator element during transcription initiation.
Published	08/28/2024	{{c1::TAF6}} and {{c1::TAF9}} bind the downstream promoter element in initiation of transcription.
Published	08/28/2024	{{c1::TNIIF}} bind to R{{c2::NA polymerase II}} and escorts it to the initiation complex during transcription
Published	08/28/2024	{{c1::Transcription factors}} bind to specific DNA sequence at the enhancer sites
Published	08/28/2024	The basic helix-loop-helix factors can act as both {{c1::activators}} and {{c1::repressors}} of transcription
Published	08/28/2024	Homeodomains have {{c1::3 helices}} and helix {{c2::3}} contacts DNA
Published	08/28/2024	After the ligand bind, the first step in the Jak-STAT pathway is {{c1::autophophorylation of Jak}}
Published	08/28/2024	The purpose of the Jak-STAT pathway is to {{c1::activate transcription}} through {{c2::translocation of STAT's to the nucleus}}
Published	08/28/2024	The Notch signaling pathway both turns {{c1::on}} and {{c1::off}} transcription.
Published	08/28/2024	Notch affects transcription through activation of {{c1::basic helix-loop-helix}} proteins
Published	08/28/2024	When {{c1::HAT}} is active, the histones become {{c2::acetylated}} and the DNA becomes {{c3::less tight}}.
Published	08/28/2024	When {{c1::HDAC}} is active, this histones are {{c2::deacetylated}}, and the DNA becomes {{c3::tighter}}.
Published	08/28/2024	In general, methylation turns genes {{c1::off}}.
Published	08/28/2024	Rho-{{c2::independent}} termination involves the formation of a {{c1::hairpin/step loop}}.
Published	08/28/2024	Rho-{{c1::dependent}} termination works by unwinding the DNA-RNA hybrid using {{c2::ATP}}.
Published	08/28/2024	Rho-dependent and rho-independent termination are used in {{c1::prokaryotic}} transcription termination.
Published	08/28/2024	RNA polymerase {{c1::I}} in eukaryotes requires a specific termination factor that binds to the end of the {{c2::r}}RNA in order to terminate transcip…
Published	08/28/2024	{{c1::RNA polymerase III}} in eukaryotes uses a {{c2::series of U residues}} to terminate transcription.
Published	08/28/2024	What two things occur to mRNA before it is degraded?
Published	08/28/2024	In RNA pol I intitiation, the {{c1::TAF and TBP complex}} binds to the DNA and recruits RNA pol 1
Published	08/28/2024	In RNA pol 1 transcription, {{c1::2 UBF}} bind to the DNA first and cause a bend in the DNA.
Published	08/28/2024	In RNA pol III initiation, {{c1::TFIIIC}} must first bind to the A and B boxes.
Published	08/28/2024	{{c1::B", TBP, and BRF}} bind to TFIIIC and recruit {{c2::RNA pol III}}
Published	08/28/2024	In 5S-rRNA transcription, {{c1::TFIIIA}} first binds to the C box.
