Which of the following is FALSE? Sigma domain 3.2 makes direct contact with the 5'-end of the nascent transcript. Lambda repressor can activate trarscription by binding a site that overlaps the -35 region of its own promoter. This allows the Lambda repressor to stabilize sigma's binding to the promoter. A helical domain of the CTD of the alpha subunit makes contact with the minor groove of the DNA at the UP element. The GreA and GreB proteins cause RNA polymerase to process the 3-end of the nascent transcript in order to reinitiate after a stall. Sigma 54-dependent promoters require cyclic AMP and CAP to melt the DNA

The a/a operon is an inducible operon that controls the production of the sugar arabinose. When arabinose is present in a bacterium it binds to the protein AraC, and the complex binds to the initiator site to promote transcription. In this scenario, AraC is a(n). activator inducer repressor operator
A scientist compares the promoter regions of two genes. Gene A’s core promoter plus proximal promoter elements encompasses 70bp. Gene B’s core promoter plus proximal promoter elements encompasses 250bp. Which of the scientist’s hypotheses is most likely to be correct? More transcripts will be made from Gene B Transcription of Gene A involves fewer transcription factors Enhancers control Gene B’s transcription Transcription of Gene A is more controlled than transcription of Gene B.

A normal mRNA that reads 5’ - UGCCAUGGUAAUAACACAUGAGGCCUGAAC- 3’ has an insertion mutation that changes the sequence to 5' -UGCCAUGGUUAAUAACACAUGAGGCCUGAAC- 3’. Translate the original mRNA and the mutated mRNA, and explain how insertion mutations can have dramatic effects on proteins. (Hint: Be sure to find the initiation site.)
A scientist mutates elF-2 to eliminate its GTP hydrolysis capability. How would this mutated form of elF-2 alter translation? Initiation factors would not be able to bind to mRNA The large ribosomal subunit would not be able to interact with itiRNA transcripts tRNAi-Met would not scan mRNA transcripts for the start codon elF-2 would not be able to interact with the small ribosomal subunit.
8 There is a promoter of a tumour suppressor gene in a mutant cancer cell line, and discover that instead of a nucleosome free region 5’ of the transcription start site there are nucleosomes bound. What would be the likely consequence on transcription of this gene? I am not sure about what is the outcome, normally it binds to the nucleosome free region 5' of the transcription start site to initiate transcription. Now, it binds with nucleosomes. What will happened? Is the DNA cannot transcripted successfully? Due to the transcription needs a naked DNA to process while in nucleosomes, DNA has been wrapped up. Thank you.

1. In a couple of sentences, explain how eukaryotic activator proteins (that are usually gene-specific transcription factors) can enhance transcription even when bound to sequences hundreds or thousands of nucleotide pairs away from a gene’s promoter. 2. Describe three common characteristics of transcription factors. The characteristics may relate to structure, or mechanism of action (PLEASE ANSWER BOTH PLEASE)
2b) 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?
