Example sentences for: cosmid

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

  • The simplest explanation is that integrase was provided in trans by a second cosmid transiently present in the original transformant, and indeed, M. smegmatis bacteria carrying an integrated copy of the 4-kb plasmid can be readily isolated following electroporation of a mixture of the 4-kb plasmid and a plasmid that expresses integrase (unpublished results).

  • PCR, DNA sequence, and Southern blot data indicated that the recovered cosmid was the same as the cosmid integrated in the sur3 genome (data not shown).

  • In this study, the enrichment process resulted in the isolation of two strains containing small, integrated plasmids rather than the expected 30-50 kb cosmids [ 20 ] . Small plasmids corresponding to the integrated ones were present in the original E. coli (pYUB178:H37Rv) cosmid library.

  • Cosmids carrying M. tuberculosis genes [ 20 ] were electroporated into M. smegmatis LR222 to create a library of M. smegmatis transformants, each of which carries a pYUB178::H37Rv cosmid integrated into its chromosome.

  • The observation that the sur2 clone contains an integrated plasmid corresponding to the plasmid isolated from the cosmid library suggests that either a) the hybrid protein retains integrase activity, b) the plasmid inserted into the attachment site by homologous recombination between attP and attB, or c) a functional integrase was provided in trans by a second cosmid transiently present in the original transformant or by a gene present in the M. smegmatis LR222 genome.
