R-plasmids contain genes for antibiotic resistance and they can be transferred among bacteria. It is common for gut bacteria of humans and other animals to spread antibiotic resistance this way. It is a problem for humans because many bacteria have become resistant to multiple antibiotics.
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.
The two types of DNA plasmids found in microorganisms are conjugative plasmids and non-conjugative plasmids. Conjugative plasmids are able to transfer genetic material between bacteria, while non-conjugative plasmids do not have this capability.
plasmids are very useful in recombinant DNA technology because ; 1. it has own origin of replication. 2.it has some selective markers like ; Amp^r, ter^r etc. 3. it has unique recognition sequence . 4.it has specific restriction sites . 5. it is small in size because in RDT foreign DNA is inserted , if the vector is large sized then after insertion it will creat problem . but due to the small size plasmids donot creat any problem.
No, it's vise versa. Plasmids are used in and by the prokaryotes.
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.
No, not all eukaryotic cells have plasmids. Plasmids are small, circular DNA molecules that are typically found in prokaryotic cells. Eukaryotic cells primarily contain their genetic material within the nucleus and do not rely on plasmids for their genetic information.
Plasmids are classified as: 1. F plasmid 2. R plasmid 3. Col plasmid F plasmids for fertility factor, it transfers its plasmid to the non fertile making it fertile. R plasmid for certain antibiotic resisitivity..for eg, ampicillin resistance. Col are certain proteins which when produced doesnt let other organisms to invade its cell.

bacteria
Plasmids can be found in both plant and animal cells. They are small, circular DNA molecules that can replicate independently of the cell's chromosomal DNA. Plasmids are commonly used in genetic engineering and biotechnology applications.
Plasmids are commonly found in bacteria and archaea. They are small, circular DNA molecules that exist outside the chromosomal DNA of the organism. Some yeast and plant cells can also contain plasmids.
