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 bacteria
- resistance plasmids (R-plasmids) = determines the bacteria's resistance to anti-infective agents
What else can I help you with?
Small DNA loops are called?
Small DNA loops are called plasmids. Plasmids are small, circular DNA molecules that are separate from the chromosomal DNA of a cell. They are often found in bacteria and can replicate independently.
Extrachromosomal DNA in prokaryotic cells can be found in the form of?
Extrachromosomal DNA in prokaryotic cells can be found in the form of plasmids, which are small circular DNA molecules that replicate independently from the chromosomal DNA. Plasmids can carry genes that provide bacteria with additional functions, such as antibiotic resistance or virulence factors.
Are plasmids found in plant or animal cells or both?
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.
What types of vectors are used to carry DNA from one species into the DNA of another species?
The two main types of vectors used are plasmids and viruses. Plasmids are circular DNA molecules found in bacteria that can be engineered to carry foreign DNA. Viruses, such as retroviruses or adenoviruses, can also be used as vectors to deliver genetic material into a host cell's DNA.
What can be found freely floating around in a bacterium but not in a flower?
Plasmids, which are small circular DNA molecules that can replicate independently from the bacterial chromosome, can be found freely floating around in a bacterium but not in a flower. Flowers do not typically contain plasmids and rely on their nuclear DNA for genetic information.

Small accessory chromosomes found in bacteria and useful in recombinant DNA procedures are called?

What type of organisms have plasmids?
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.
Who discovered plasmid?
The discovery of plasmids is credited to Joshua Lederberg and Esther Lederberg in the 1950s. They identified plasmids as small, circular DNA molecules that are found in bacteria and can replicate independently of chromosomal DNA.
Little rings found in the DNA of bacteria called?
Plasmids are small, circular DNA molecules found in bacteria that replicate independently of the bacterial chromosome. They often carry genes that can provide benefits to the bacteria, such as antibiotic resistance. Plasmids can be transferred between bacteria through a process called conjugation.
What can be found freely floating around in a bacterium but not in a flower?
Plasmids, which are small circular DNA molecules that can replicate independently from the bacterial chromosome, can be found freely floating around in a bacterium but not in a flower. Flowers do not typically contain plasmids and rely on their nuclear DNA for genetic information.
What are Extra-chromosomal DNA particles capable of independent replication are called?
Extra-chromosomal DNA particles capable of independent replication are called plasmids. Plasmids are circular DNA molecules found in bacteria that can replicate independently of the chromosomal DNA. They often carry additional genes that can provide advantages to the bacteria, such as antibiotic resistance.
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.
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.
