How are prophages and bacterial plasmids similar?
Prophages and bacterial plasmids are both genetic elements found in bacteria. They can replicate independently from the bacterial chromosome and confer certain traits to the bacterial host, such as antibiotic resistance. Additionally, both prophages and plasmids can integrate into the bacterial chromosome and be vertically inherited during cell division.
How are plasmids removed from bacterial cells?
Well, sweetheart, plasmids can be removed from bacterial cells through a process called curing, where the bacteria are treated with certain chemicals or heat to encourage the loss of the plasmid. Alternatively, you can also use techniques like centrifugation or filtration to physically separate the plasmids from the bacterial cells. Just remember, plasmids may be small, but they sure can be a pain in the butt to get rid of!
Describe the essential features of the use of bacterial plasmid?
Bacterial plasmids are small, circular DNA molecules that replicate independently of the bacterial chromosome. They can carry genes that provide advantages to bacteria, such as antibiotic resistance or the ability to metabolize specific compounds. Plasmids can be manipulated in the lab and used as vectors to introduce genes into bacteria for research or industrial purposes.
Do all microbes have plasmids?
No, not all microbes have plasmids. Plasmids are small, circular pieces of DNA that are separate from the microbial genome. While plasmids are common in many bacteria, they are not present in all microbes.
What happens to plasmids during conjugation?
During conjugation, plasmids are transferred from one bacterial cell to another through a conjugation bridge formed by sex pili. The plasmids can contain genes that may provide beneficial traits such as antibiotic resistance or the ability to metabolize certain substances. This transfer allows for the exchange of genetic material between bacterial cells.
Can plasmids self-replicate within a bacterial cell?
Yes, plasmids can self-replicate within a bacterial cell.
Can a bacteraial plasmid replicate independently of the bacterial chromosome?
Yes, bacterial plasmids can replicate independently of the bacterial chromosome. Plasmids contain their own origin of replication, allowing them to replicate autonomously within the bacterial cell. This characteristic is advantageous for manipulating plasmids in genetic engineering experiments.

In a bacterial cell, where would you find the DNA plasmids?
cytoplasm

What types of plasmids allows a bacterial cell to kill its competitors?
Plasmids can carry genes for producing toxins like bacteriocins or restriction enzymes that can inhibit or kill bacterial competitors, promoting the survival and proliferation of the host cell. These plasmids confer a competitive advantage to the host bacteria in environments where resources are limited.
How many plasmids in a bacterial cell?
A bacterial cell can contain multiple copies of the same plasmid or different types of plasmids, which can range from zero to many copies depending on the specific species and growth conditions of the bacteria. The number of plasmids in a bacterial cell can vary and is not fixed.
What is a promiscuous plasmids?
A promiscuous plasmid is a type of DNA molecule that can be transferred between different bacterial cells through processes such as conjugation, transformation, or transduction. These plasmids often carry genes that promote their own transfer and can spread rapidly among bacterial populations.

Which enzyme is Known as Genetical or Genetic Knife?
restriction endonuclase enzyme (made in bacterial plasmids)
