A pre-initation complex (PIC) is required for transcription to begin. State which TFII protein has catalytic function.
Mechanisms that inhibit TE activity include theproduction of transposition repressors throughalternative splicing and the action of _________ thatblock TE transcription.
Some transcription regulators bind to DNA andcause the double helix to bend at a sharp angle. Such“bending proteins” can affect the initiation of transcrip-tion without directly contacting any other protein. Can youdevise a plausible explanation for how such proteins mightwork to modulate transcription? Draw a diagram that illus-trates your explanation.
In your own words, describe the difference between rhodependent and rho-independent termination of transcription in prokaryotes.
. In an effort to determine the location of an operator sitefor a negatively regulated gene, you have made a seriesof deletions within the regulatory region. The extent ofeach deletion is shown by the line underneath the sequence, and the resulting expression from the operon(i = inducible; c = constitutive; − = no expression) isalso indicated....

A pre-initiation complex (PIC) is required for transcription to begin. State in which TFII protein has a catalytic function.
Which statement is false: A) Each type of protein ( ex: hemoglobin vs trypsionngen) varies in the length and amino acid sequence of its peptide B) After the rpocess of transcription is complete, the mRNA that is produced will continue being tranlsated by ribosomes for the rest of the cells life. mRNA never breaks down C) A ribosome will bind to an mRNA and will translate the sequence by reading one codon at a time and adding one amino acid to the peptide chain. It will stop the translation once it encounters a stop codon D) The gene for a protein provides the information on the legth of the peptide, along w the amino acid sequence so the protein can be synthesized by a ribosome E) Once mRNA has left the nucleus, ribosomes will bind to it and will follow the instructions in its sequence to make the new protien

You are studying an operon containing three genesthat are cotranscribed in the order hupF, hupH, andhupG. Diagram the mRNA for this operon, showingthe location of the 5′ and 3′ ends, all open readingframes, translational start sites, stop codons, transcription termination signals, and any regions thatmight be in the mRNA but do not serve any of thesefunctions.
Once an RNA polymerase has initiated transcription, it will release the sigma factor or sigma subunit and bind other proteins known as elongation factors before it begins moving down the DNA template doing strand elongation. Briefly explain why this is necessary - why can't RNA polymerase + sigma factor do all of transcription? Be specific.
The promoter of an operon is the site to which RNApolymerase binds to begin transcription. Certain basechanges in the promoter result in a mutant site towhich RNA polymerase cannot bind. Would you expect mutations in the promoter that prevent binding ofRNA polymerase to act in trans on another copy ofthe operon on a plasmid in the cell, or only in cis onthe copy immediately adjacent to the mutated site?
