MIBO TEST 2 WITH COMPLETE
VERIFIED SOLUTIONS
dnaA - answer initiator protein, binds to oricC, (origin)
dnaB - answer helicase,unwinds helix to expose template strands
dnaG - answer Primase synthesizes RNA primers
dna pol III - answer major replication enzyme
dna pol I - answer replaces RNA primer with DNA
dna gyrase - answer relieves positive DNA supercoiling
The oriC origin is a 245-bp sequence that includes a series of repeats bound by specific
replication factors. - answer
•In which of the following enzymes would you expect to find a mutation if a bacterial cell shows
defects in both chromosome packing and DNA replication? - answer topoisomerase
Negative supercoiling of the DNA is_______. - answer performed by dna gyrase
The sigma factor is directly required for - answer transcription initiation
In E. coli, why is sigma-70 considered the "housekeeping" sigma factor? - answer It keeps
essential genes and pathways operating.
