Why do some plasmids contain a gene for resistance to antibiotic?
Plasmid contain a few genes including antibiotic resistance genes .Bacteria are highly active metabolically and many mutation are produced in them . These genes are produced by evolution.
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.
What is the extra ring called in bacteria?
The extra ring found in bacteria is called a plasmid. Plasmids are small, circular pieces of DNA that can replicate independently of the bacterial chromosome. They often contain additional genes that can provide advantages to the bacterial cell, such as antibiotic resistance or the ability to metabolize certain substances.
Is human cell contain plasmid?
Plasmid is the property of prokaryotic cell i.e. of bacteria generally no mamalian cell have plasmid but ya there can be chances to have lillte part of DNA sequence to be simillar that of plasmid DNA sequence in prokaryotes
What type of gene is used to distinguish bacteria that carry a plasmid containing foreign DNA from those that don' t?
The plasmid that contains foreign DNA is engineered to also carry an antibiotic resistance gene. This antibiotic resistance gene codes for a protein that is able to inactivate an antibiotic thus keeping the cell alive. In the absence of the antibiotic resistance gene, the cells would not survive when exposed to an antibiotic. After transfection (the process of inserting the plasmid carrying the foreign gene into cells), the cells are gown in media containing an antibiotic. Cells that contain the plasmid (and therefore contain the antibiotic resistance gene) are able to survive in this medium. Cells that do not contain the plasmid (and therefore lack the antibiotic resistance gene) do not survive in this medium. The process described above is called selection
Why do plasmids contain a gene for antibiotic resistance?
Plasmids contain antibiotic resistance genes because these genes provide a survival advantage to the bacteria in the presence of antibiotics. Bacteria can pick up plasmids with antibiotic resistance genes through horizontal gene transfer, allowing them to survive in environments with antibiotic exposure. This is a common mechanism for bacteria to acquire resistance traits and poses a challenge for antibiotic treatment.
What are r plasmids and why are these a problem to humans?
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.

What are the common features and functions of eukaryotic plasmids?
Eukaryotic plasmids are small, circular DNA molecules found in the cytoplasm of eukaryotic cells. They often contain genes that provide benefits to the cell, such as antibiotic resistance or the ability to produce certain proteins. Plasmids can replicate independently of the cell's chromosomal DNA and are commonly used in genetic engineering and research.
Do fungal cells have plasmids?
Yes, fungal cells can contain plasmids. Plasmids are small, circular DNA molecules that can exist independently of the fungal cell's chromosomal DNA. They can carry extra genes that may confer certain advantages, such as antibiotic resistance or toxin production, to the fungal cell.

Plasmids are circular pieces of DNA that exist in addition to the chromosomal DNA of certain bacteria and yeast?
Plasmids often contain genes that give organisms various abilities, such as antibiotic resistance or the ability to metabolize certain compounds. They can be passed between bacteria through horizontal gene transfer, allowing for the rapid spread of these traits within a bacterial population. Plasmids are used extensively in biotechnology as vectors for introducing foreign genes into organisms for research or commercial purposes.
What is plasmid and what advantage might a bacterium gain by acquiring one?
A plasmid is a small, circular DNA molecule that is separate from the bacterial chromosome. Bacteria can gain advantages by acquiring plasmids that contain genes for antibiotic resistance, toxin production, or the ability to metabolize new substances. This allows them to adapt to changing environments or to compete more effectively with other organisms.
What are two features that make plasmids useful for transforming cells?
Small size: Plasmids are small, circular pieces of DNA that are easily taken up by cells, making them efficient vectors for introducing new genetic material. Selectable markers: Plasmids often contain genes for antibiotic resistance or other selectable markers, allowing researchers to easily identify and isolate cells that have successfully taken up the plasmid during transformation.
