Recombinant plasmids behavior

Table 2. Phenotypic Behavior of Recombinant Plasmid pAT9 in a Continuous Culture of the Transformant B. stearothermophilus CU21(pAT9) culture medium, LMPK and 48 C.

Plasmid DNAs. Plasmids are nucleic acid molecules capable of intracellular extrachromosomal repHcation. Usually plasmids are circular DNA species, but linear and RNA plasmids are known. In nature, plasmids can assume a variety of lifestyles. Plasmids can recombine into the host chromosome, be packaged into vims particles, and repHcate at high or low copy number relative to the host chromosome. Additionally, their information can affect the host phenotype. Whereas no single plasmid is usually capable of all these behaviors, the properties of various plasmids have been used to constmct vectors for a variety of purposes.
