Example sentences for: phages

How can you use “phages” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Genes from each class, that is, native genes, potentially transferred genes (LTG), IS and phages, of the four groups of bacterial genomes ( Escherichia , Salmonella , Helicobacter , and Streptococcus ) were then retained for codon-usage analysis when their lengths were greater than 150 base-pairs (bp) to avoid artifacts linked to stochastic variations that might happen in shorter genes.

  • Most of the acquired genes have no known functions, though a few are annotated as membrane proteins, phages or IS.

  • These include the cell-wall hydrolases typified by the Pal protein from streptococcal phages [ 24, 25] and the amidase domain of the bacterial and kinetoplastid GSPS [ 26].

  • Some of the morons have been shown to be related to other bacterial genes, suggesting that they may at first have been host genes integrated in the phage genome [ 22 ] . These genes may then have diverged rapidly because phages are known to have evolutionary rates orders of magnitude higher than those of bacteria [ 25 ] . Morons seem rarely to confer a direct advantage on the phage, but rather stabilize the host-prophage interaction by slightly increasing host fitness [ 20 ] . Therefore, they may undergo weaker selection pressure than genes directly involved in the phage life-cycle and be more sensitive to the mutational bias inherent to parasitic sequences [ 13 ] . From our results, it appears that whatever the nature of the organism in which the gene was first recruited, its compositional characteristics no longer represent its previous genome context.

  • The isolated cDNA-bearing phages were rescued to plasmids according to the manufacturer's instruction.
