Landsat has been collecting data since:

Addition of ciprofloxacin (a quinolone antibiotic) to purified plasmid would result in which conformation in the image below? A or B?  

The __________ of the CRISPR locus serve(s) as the “memory” of the previous infection.

A genetic toggle switch has Repressor A (inhibits Gene B, inactivated by IPTG) and Repressor B (inhibits Gene A, inactivated by heat). The system is currently in State A (high Repressor A, low Repressor B). What happens when a high concentration of IPTG is added?

Match each DNA repair mechanism listed below (top to bottom) with the type of DNA damage it primarily repairs. Repair Systems•    Methyl-directed mismatch repair•    Photoreactivation (photoactivation)•    Homologous recombination•    Base excision repair•    Nonhomologous end joining (NHEJ)•    SOS repair DNA Damage TypesA.    Thymine–thymine (T–T) dimers caused by UV lightB.    Chemically modified or damaged single basesC.    Error-prone repair of double-strand breaksD.    Replication errors producing base–base mismatchesE.    Error-proof repair of double-strand breaks F.    Global emergency response that allows translesion synthesis across damaged DNA

A mutant strain of coli lacks functional β-galactosidase (LacZ) but still produces functional LacI repressor and LacY permease. The cells are grown in medium containing lactose but no glucose. What is the most likely effect on transcription from the lac operon?

Which of the following is NOT true about the initiation of transcription?

During prokaryotic transcription, which statement best describes how the RNA polymerase (RNAP) holoenzyme manages the DNA duplex in the transcription bubble?

Which RNA molecule within the prokaryotic ribosome base-pairs with the Shine–Dalgarno sequence of mRNA during translation initiation?
