If 2 genes are close together along the chromosome, a bacteriophage may package a single piece of the chromosome that carries both genes and transfer that piece to another bacterium This document is highly rated by Biotechnology Engineering (BT) students and has been viewed 537 times. CLASSIFICATION AND STRUCTURE OF MICROORGANISMS. A. conjugation B. transformation C. replication D. transduction. When this bacteriophage infects new bacterial cell, it transfer that DNA in to recipient cell. Winner of the Standing Ovation Award for “Best PowerPoint Templates” from Presentations Magazine.
