Plasmids are unique to what?
Plasmids are unique to bacteria and other prokaryotic organisms. They are small, circular DNA molecules that can replicate independently from the host cell's chromosomal DNA. Plasmids often carry genes that provide the host with additional functions, such as antibiotic resistance or the ability to metabolize certain nutrients.
Which kingdom contains plasmids?
Plasmids are primarily found in the kingdom Monera, which includes bacteria and archaea. These small, circular DNA molecules exist independently of chromosomal DNA and can carry genes that provide advantages, such as antibiotic resistance. Plasmids are also utilized in genetic engineering across various organisms, but they naturally occur in prokaryotic cells.
Are plasmids self-replicating?
Yes, plasmids are self-replicating circular DNA molecules that exist independent of the bacterial chromosome. They carry genes that provide advantages to the host organism and can replicate within the host cell.
What type of plasmid is the source of the problem with antibiotic resistance?
The source of antibiotic resistance is often plasmids known as R plasmids, which carry genes that confer resistance to antibiotics. These plasmids can be transferred between bacteria, spreading antibiotic resistance throughout microbial populations.
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.
Do mitochondria have plasmids?
No, mitochondria do not have plasmids. Plasmids are small, circular DNA molecules often found in bacteria and other prokaryotic organisms, but not in eukaryotic organelles like mitochondria. Mitochondria have their own separate DNA that is usually in the form of a circular chromosome.
What cells have plasmids?
The prokaryotes, bacteria being the main ones.

Why are plasmids essential for recombinant DNA technology?
Plasmids are essential for recombinant DNA technology because they are small, circular DNA molecules that can be easily manipulated and transferred between different organisms. They serve as vectors to carry foreign DNA into host cells, allowing for the creation of genetically modified organisms.
Why are plasmids important in genetic engineering and biotechnology?
Plasmids are important in genetic engineering and biotechnology because they are small, circular DNA molecules that can be easily manipulated and transferred between different organisms. This allows scientists to introduce specific genes into cells, enabling them to produce desired proteins or traits. Plasmids are also used as vectors to deliver therapeutic genes in gene therapy and to create genetically modified organisms for various applications.
How is the artificial manipulation of plasmids used for technological applications?
Artificial manipulation of plasmids is used to introduce specific genes into organisms for various technological applications, such as producing pharmaceuticals, biofuels, and enzymes. This technique allows for the genetic modification of organisms to enhance their abilities to produce desired products. Additionally, plasmids can be engineered to carry genes that confer resistance to specific environmental stresses or pathogens, making them useful in bioremediation and as tools for studying gene function.

Do they prokaryotes or bacteria mean nucellus not nucleus?
They are non-nucleated organisms and have nuclear material in the form of dense DNA clusters or plasmids

The source of antibiotic resistance is often plasmids known as R plasmids, which carry genes that confer resistance to antibiotics. These plasmids can be transferred between bacteria, spreading antibiotic resistance throughout microbial populations.
What are the 2 types of DNA plasmids found in microorganisms?
Plasmids are autonomous DNA molecules of varying size which are localized within the cytoplasm of bacteria. There are two kinds:virulence plasmids = determines the virulence factors of the bacteriaresistance plasmids (R-plasmids) = determines the bacteria's resistance to anti-infective agents
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.
