1) What structural motif is mostcommonly used by transcription factors in binding toDNA?
a) Zinc- finger
b) Helix-turn-helix
c) Homeodomain
2) Kozakâs rules for translation are similar to those fortranscription in prokaryotes in that they both contain consensussequences. In prokaryotes, the promoter consensus sequences are at-35 and -10. Where is the consensus sequence for translationalinitiation according to Kozakâs rules?
a) -6 to + 10
b) -12 to -2
c) +1 and +10
3) A culture of E.coli bacteria is used to establish severalsubcultures. Each subculture is then plated and individual coloniesthat grow on the agar plates are then tested for their sensitivityto the bacteriophage T1. There is a spectrum of sensitivities wheresome plates have a high number of resistant colonies and someplates had very few. This data supports which theory?
a) Physiological adaptation theory
b) Random mutation theory
c) Neither theory
