Exam 3: BIO1201/ BIO 1201 (Latest 2024/ 2025 Update) | Questions and Verified Answers| 100% Correct| Grade A – LSU Q: How are genes coordinately controlled in eukaryotic cells? Coordinately controlled genes in eukaryotic cells share a set of control elements. Coordinately controlled genes in eukaryotic cells are activated by the same chemical signals. Coordinately controlled genes in eukaryotic cells are located together on the same chromosome. Answer: Coordinately controlled...

True or False: Much research has been done on sRNAs (small noncoding RNA) and they have been extremely well-characterized for their function. FALSE TRUE/FALSE: A bacterium that can grow well on minimal medium is an example of a prototroph. TRUE Enzyme Acts as a catalyst for...to bring about a specific biochemical reaction Operon Clusters of genes and...under the control of a single promoter. Gratuitous inducer Activates genes but not be metabolized by the encoded enzymes Structural g...

The tryptophan operon is a repressible operon that is: - ANSWER-Turned off whenever tryptophan is added to the growth medium. The lactose operon is likely to be transcribed when: - ANSWER-The cyclic AMP and lactose levels are both high within the cell. For a repressible operon to be transcribed, which of the following must occur? - ANSWER-RNA polymerase must bind to the promoter, and the repressor must be inactive. Which of the following, when taken up by the cell, binds to the represso...

Bio 115 WVU Final (Dr. Barry) Questions and Answers Graded A+ For e. coli , the lacl repressor gene is expressed when? The lacl repressor gene is always expressed Where does the lacl repressor gene attach The lacl repressor gene codes for a protein which attaches to the lac operon operator In the absence of lactose, does the lacl repressor gene bind to DNA Yes, in the absence of lactose, the lacl repressor gene binds to DNA preventing transcription; this is an example of negative...

negative regulation for the lac operon when ~ see a repressor positive regulation in lac operon when ~ camp cap what are camp cap and where to they bind? activator/repressor? trans/cis? pos/neg regulation? ~ operon, initiate transcription in absence of glucose. they are an activator. trans. and positive regulation restriction sites in normal genes ~ don't have them naturally, added through primers via PCR Predict what would happen if you swapped the location of the promoter and th...

You discover a new bacterial operon that is induced by the presence of lead. You find a mutation that results in a mutation in the operator that changes the binding sequence so that the repressor is always bound to it. Would this mutation be rescued by a plasmid with a wild type copy of the operon and why? correct answers Yes, because the repressor would still be able to bind to the operator in the plasmid allowing for normal expression from the plasmid Why is it difficult to find a treatment...
