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!
What else can I help you with?
Do cells take up more plasmids in some conditions and less in others?
Bacterial cells do not normally take up plasmids. However, scientists can use tricks to make them do so.
What are the small DNA fragments found in bacterial cells?
The small DNA fragments found in bacterial cells are known as plasmids. Plasmids are circular, double-stranded DNA molecules that can replicate independently of the bacterial chromosome. They often carry genes that confer advantageous traits, such as antibiotic resistance or the ability to metabolize unusual substances. Plasmids play a key role in horizontal gene transfer, allowing bacteria to share genetic material and adapt to changing environments.
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.
What are small DNA fragments that occur in many bacterial cells?
Small DNA fragments that occur in many bacterial cells are known as plasmids. Plasmids are circular, double-stranded DNA molecules that replicate independently of the chromosomal DNA. They often carry genes that provide beneficial traits to bacteria, such as antibiotic resistance or the ability to metabolize unusual substrates. Plasmids play a crucial role in horizontal gene transfer, facilitating genetic diversity among bacterial populations.
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 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.
What cells have plasmids?
The prokaryotes, bacteria being the main ones.
Do cells take up more plasmids in some conditions and less in others?
Bacterial cells do not normally take up plasmids. However, scientists can use tricks to make them do so.
Do all eukaryotic cells have plasmids?
Most plasmids are found in prokaryotic cells, but a few eukaryotic cells also have plasmids. An example of a eukaryote with plasmids is the unicellular yeast Saccharomyces cerevisiae.
Can plasmids self-replicate within a bacterial cell?
Yes, plasmids can self-replicate within a bacterial cell.
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.

Exogenous DNA can be inserted into bacterial cells in order to alter their genetic makeup and support expression of new protein products What are they?
Plasmids.

During transformation of bacterial cells chemicals that weaken bacterial membranes or pulses of electricity that temporarily tear tiny holes in the cells are used to do what?
Enable the faster and more numerous transfer of plasmids into the bacteria. (C for PLATO users.) ~Æ
