Plasmid DNA can be separated from chromosomal DNA by the alkaline lysis method. Cells are first lysed with a strong alkaline buffer containing SDS and NaOH. A series of steps involving precipitation,...
Genome DNA is the primary DNA of a cell and it drives the cell's primary functions. When considering the genome of a lifeform it is only the genomic DNA that is considered. Plasmid DNA is an extra...
Alcohol is a dehydrating agent that can disrupt proteins in the cell membrane. This breaks open the cell and liberates the plasmid(s) into the bulk of the solutuion
Ok i think this is right. Plasmid DNA is supercoiled and smaller whereas chromosomal DNA is larger and more fragile. So plasmid DNA isolation is a lot harsher, harsher techniques and harsher...
To separate the bacterial chromosomal DNA and sheared DNA from plasmid DNA, NaOH is often used. Chromosomal DNA and sheared DNA are both linear, whereas plasmid DNA is circular. When the solution is...
