reported that NGR234 contains two plasmids of M3×108 and 4.5×108, it seems unlikely that a second plasmid exists. It is true, however, that some nodulation and other symbiotic genes map to the chromosome. (Incidentally, the fixABC cluster is present on pNGR234a.)...
Figure 1-8.Plasmid map for pEGBGFP35S However, you don’t have to use GFP; you can use any reporter system you choose to generate an expression signal that can be assayed. Jay Hanson has posteda short videoshowing how to set up and use the gene gun. ...
particularly for introducing modifications in gene coding regions. This method involves inducing frameshift mutations, altering intron splice junctions to encourage intron skipping, or creating large fragment deletions (Zhang et al.2022a). Various strategies have emerged to reduce target gene expression, i...
Explain how some bacteria are able to resist penicillin action. Explain the steps involved in growing an uncontamintaed culture of bacteria on nutrient agar jelly. Describe ways to help limit the creation and spread of antibiotic resistant bacterial strains. What is a p...
To re-engineer them for delivering human genes, scientists "clean out" the harmful parts of the virus, insert a human gene into the virus' genetic material and then inject the virus into the body. Another type of vector is a plasmid, a ring of bacterial DNA into which human genes can ...

(refs 3,4). Thus, although Morrisonet al.5reported that NGR234 contains two plasmids ofMr3×108 and 4.5×108, it seems unlikely that a second plasmid exists. It is true, however, that some nodulation and other symbiotic genes map to the chromosome6. (Incidentally, thefixABCcluster is ...
genes encoding proteins that make a bacterial cell resistant to a particular antibiotic are encoded onR plasmids. R plasmids, in addition to their genes for antimicrobial resistance, contain genes that control conjugation and transfer of the plasmid. R plasmids are able to transfer between cells of...
of residues in multiple locations within this poly-Gly sequence and determining rates of substrate degradation by ClpAP, we establish an initial map of how substrate side chains within the linker and their predicted locations within the two rings of ClpA’s axial channel contribute to grip. We...
Using a plasmid reporter assay, TFs and co-factors are tethered to various inactive enhancers to test their ability to restore enhancer activity. This shows that a wide variety of factors are activating or repressing. They sometimes function in a context-dependent manner, showing that TFs and co...
