If the bacterial DNA sequence is Leu Met Att Gal Bio, which of the genes can be transferred via specialized transduction?
A. Leu and Met B. Met, Att and Gal C. Gal and Bio D. Met and Gal only
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.
