Sentence:  After the <WSD>transducing</WSD> phage DNA is introduced into the recipient cell genome, the cell acquires, in addition to phage genes, genetic information that originated from the phage's previous host. Thus, in specialized transduction, the phage serves as a vector for transferring genes from one cell to another; only cellular genes that are close to the viral genome integration site are transducible by this mechanism. 
Meaning of the word marked with <WSD> tags:  To transfer or copy genetic material from one cell or virus into another.
