<h3>Chromosomal Integration </h3> | <h3>Chromosomal Integration </h3> | ||
A small plasmid with few expressed genes may not affect the current output of S. oneidensis to a significant degree, but a large plasmid with many expressed genes (such as our secondary naphthalene degradation plasmid) significantly impairs the growth and metabolism of S. oneidensis. Integrating the naphthalene degradation operon into the chromosome of S. oneidensis may help partially alleviate the energy cost of replicating several copies of a huge plasmid. | A small plasmid with few expressed genes may not affect the current output of S. oneidensis to a significant degree, but a large plasmid with many expressed genes (such as our secondary naphthalene degradation plasmid) significantly impairs the growth and metabolism of S. oneidensis.

In addition to alleviating the stress caused by expressing a giant operon, integrating our genetic parts into the chromosome eliminates the need to design a selective pressure for S. oneidensis to maintain extrachromosomal DNA. | In addition to alleviating the stress caused by expressing a giant operon, integrating our genetic parts into the chromosome eliminates the need to design a selective pressure for S. oneidensis to maintain extrachromosomal DNA. | ||
