Answer» Right option is (d) Met and Gal only For explanation: Att site is merely NECESSARY for incorporation of the VIRUS. In specialized transduction the SITES directly beside the attachment point of the virus can be mistakenly excised with the part of viral gene. Here this PHENOMENON will occur only in CASE of Met and Gal.
