Permeability


Definition:

  • (n.) The quality or state of being permeable.

Example Sentences:

  • (1) We conclude that chloramphenicol resistance encoded by Tn1696 is due to a permeability barrier and hypothesize that the gene from P. aeruginosa may share a common ancestral origin with these genes from other gram-negative organisms.
