1.   Another feature of interest to microbiologists is the presence of a latent phage, a virus that infects bacteria, whose DNA sequence is nestled inside that of Hemophilus.

2.   He also embarked on a major project, the study of viruses that infect bacteria.

3.   If the cells had survived, the copies would have burst out and infected adjacent bacteria.

4.   Ptashne started on the puzzle by studying E. coli bacteria and the lambda virus, which infects the bacteria.

5.   The two enzymes are found in viruses that infect E. coli bacteria and apparently play a role in checking for genetic defects during viral replication, Sklar said.

6.   These young phages drift off to infect more bacteria.

7.   This led him to take a course in the genetics of viruses that infect bacteria and he was instantly converted to biology, specifically to genetics.

8.   To learn more about them, and about the basic nature of heredity, the three researchers focused on bacteriophages, viruses that infect bacteria.

9.   Viruses that infect bacteria can sometimes pick up a gene from one bacterium and carry it to another.

10.   When it infects, the bacteria produces a toxin, or poison, that attacks cells.
