What is a self-transmissible plasmid?
A self-transmissible plasmid is a type of plasmid that can transfer genetic material from one bacterium to another through a process called conjugation. This plasmid carries the necessary genes for forming a conjugative pilus and transferring the plasmid DNA. Self-transmissible plasmids play a significant role in horizontal gene transfer among bacteria.
Role of Glacial acetic acid in plasmid isolation?
Glacial acetic acid is used in plasmid isolation to precipitate proteins during the process of plasmid DNA purification. It helps separate the plasmid DNA from proteins, RNA, and other contaminants, allowing for the collection of purified plasmid DNA. Additionally, acetic acid helps maintain the pH of the solution, facilitating the precipitation of contaminants while keeping the plasmid DNA soluble.
How can i know if my bacteria contain plasmid or not?
You can determine if your bacteria contain a plasmid by performing a plasmid extraction followed by gel electrophoresis to visualize the presence of plasmid DNA. Other methods include PCR amplification of plasmid-specific sequences or using molecular biology techniques like restriction enzyme digestion to confirm the presence of a plasmid.
Is the plasmid found in prokaryotic or eukaryotic cells?
The plasmid is found in prokaryotic cells.
Is plasmid DNA double stranded?
Yes, plasmid DNA is typically double stranded.
What is the role of ECORI?
It splices the genome or plasmid in a specific location (EcoRI).

Which is the plasmid that increases resistance to antibiotics?
R-plasmid
What plasmid that can degrade toluic acid?
TOL plasmid
Explain fully the role of naoh in the lysis procedure to obtain covalently closed plasmid molecules?
NaOH is used in plasmid extraction procedures to help lyse bacterial cells by denaturing proteins and breaking down cell membranes. This releases the plasmid DNA into the solution. NaOH also helps to denature the double-stranded DNA, converting the plasmid into single-stranded DNA. The addition of NaOH is followed by neutralization with an acidic solution, which helps to renature the plasmid DNA back into its covalently closed, double-stranded form.

How is RNA removed from DNA during DNA isolation?
Most often, RNA is removed using the enzyme RNAase
A plasmid is a type of?
Plasmid is extrachromosomal DNA capable of self replication.
What is a self transmissible plasmid?
A plasmid which encodes genes for its own transfer.
Role of chloroform in plasmid isolation?
Chloroform is commonly used in plasmid isolation to separate different components in a cell lysate, such as proteins, RNA, and DNA. It helps to denature proteins and disrupt cell membranes, allowing for the separation of plasmid DNA from other cellular components. Chloroform also aids in the removal of lipids and other contaminants during the purification process.
