12 Questions
What is the main objective of plasmid minipreparation?
To extract plasmid DNA from bacterial cell suspensions
Which of the following is a characteristic of plasmid DNA?
It is physically separated from chromosomal DNA
What makes plasmid DNA different from bacterial chromosomal DNA?
It can replicate independently
How does the method of plasmid minipreparation take advantage of the differences between plasmids and bacterial chromosomal DNA?
By utilizing alkaline lysis to isolate supercoiled plasmid DNA
Why is plasmid minipreparation method advantageous for isolating plasmid DNA?
Plasmids are relatively small and supercoiled compared to larger, less supercoiled bacterial chromosomal DNA
What characteristic of plasmid DNA makes it suitable for the minipreparation method?
Small size and supercoiling
In comparison to bacterial chromosomal DNA, what distinguishes plasmid DNA in the minipreparation method?
Smaller size and higher supercoiling
Why is it feasible to isolate plasmid DNA using the minipreparation method?
Plasmids are small, supercoiled DNA molecules, making them distinguishable from larger, less supercoiled bacterial chromosomal DNA
What allows for selective precipitation of the chromosomal DNA from plasmids and RNA molecules in plasmid minipreparation?
Difference in topology
In plasmid minipreparation, why is it advantageous to selectively precipitate the chromosomal DNA from plasmids and RNA molecules?
To isolate pure plasmid DNA
What differentiates plasmid DNA from bacterial chromosomal DNA in the context of plasmid minipreparation?
Topology
Which characteristic of plasmid DNA makes it suitable for the selective precipitation in plasmid minipreparation?
Circular structure
Test your knowledge on the process of isolating a plasmid from a bacterial cell and differentiating between bacterial chromosome and plasmid based on topology. Learn about the roles of each step in the process of Plasmid Minipreparation.
