Final answer:
A "mini" plasmid prep allows for the purification of plasmid DNA from bacterial cells, generating larger quantities of plasmid DNA for cloning, transfection, or RNA synthesis.
Step-by-step explanation:
A "mini" plasmid prep allows for the purification of plasmid DNA from bacterial cells. Plasmids are small circular DNA molecules that replicate independently of the chromosomal DNA and are commonly used in molecular cloning and genetic engineering. The process of plasmid prep involves breaking the bacterial cells, isolating the plasmid DNA, and purifying it for further use in cloning, transfection, or RNA synthesis. This method helps generate larger quantities of plasmid DNA required for various applications.
