  • Why does conjugation between an Hfr strain and an F- strain not result in two Hfr strains?
    Conjugation between an Hfr strain and an F- strain does not result in two Hfr strains because the F- strain does not receive the entire Hfr chromosome during conjugation.
  • What is commonly shared between bacteria through the process of conjugation?
    Genetic material, such as plasmids, is commonly shared between bacteria through the process of conjugation.
  • Which is true about bacterial conjugation?
    Bacterial conjugation involves the transfer of genetic material between bacteria, often through a pilus.
  • Which types of chemical species are capable of conjugation?
    All of the above (pi bonds, lone pairs, radicals, cations) are capable of conjugation as they can resonate.
  • What is a true effect of conjugation on chemical stability and reactivity?
    Conjugation provides stability and unique chemical reactivity due to electron delocalization.
  • What is true about conjugation in chemistry?
    Conjugation involves three or more atoms with the ability to resonate being next to each other or back to back.
  • What is the relationship between conjugation and UV wavelength?
    The higher the level of conjugation in a molecule, the higher the UV wavelength in a UV Vis spectrometer.
  • What types of atoms can participate in resonance?
    Atoms that can resonate include pi bonds, lone pairs, radicals, and cations.
