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 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.
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
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 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 is a plasmid and why is it useful to researchers?
Plasmids are important in the phases of bacterial genetics because plasmids are the small circle of DNA for bacteria and is responsible for storing and studying genes. Plasmid is used as the vehicle to genetically engineer bacteria to produce insulin.
Does a cloning vector contain promoter region?
No, not really since it is just for cloning. But their should be enough promoter/sequence to provide antibiotic resistance.

What one plate would you first inspect to conclude that the transformation occurred successfully Why?
If you transform bacteria with a plasmid containing a selection marker (such as an antibiotic resistance gene) and plate the transformed bacteria on a plate suited for selecting for plasmid-containing bacteria (such as a plate containing an antibiotic that only those bacteria with antibiotic resistance can survive), then simply inspecting whether colonies are present on the plate will suffice in determining whether the transformation succeeded. If no colonies are found, that means no bacteria got the antibiotic resistance gene on the plasmid and the transformation was unsuccessful. If some colonies are found, that means some bacteria contain the plamis containing the antibiotic resistance gene and those colonies can the transformation was successful.
Do fungal cells have plasmids?
It does not contain chloroplast because there is no any green pigment exist, and they doesn't make food by photosyntesis.
What cuts bacterial plasmids?
Enzymes called restriction endonucleases can cut plasmids. However, in order for a cut to be produced, the plasmid should contain a specific sequence of nucleotides called the restriction site
What are plasmids?
A segment of DNA independent of the chromosomes and capable of replication, occurring in bacteria and yeast: used in recombinant DNA procedures to transfer genetic material from one cell to another.
