Plasmids are circles of DNA. These have genes that can be transferred from one bacteria that has it to another. These genes can code for a protein that one cell normally doesn't code for.

This done by a process called bacterial conjugation.

When plasmids are used to produce a desired protein what happens?

When plasmids are used to produce a desired protein, the gene encoding for the protein is inserted into the plasmid. The plasmid is then introduced into a host organism, such as bacteria, which then replicate the plasmid and express the protein. This allows for large-scale production of the desired protein.

Can prokaryotes synthesize proteins?

Yes, prokaryotes can synthesize proteins. They have ribosomes and the necessary machinery to transcribe DNA into mRNA and then translate the mRNA into proteins. The process of protein synthesis in prokaryotes occurs in the cytoplasm.


What is needed to synthesize protein?

DNA


What organelles are found only in bacteria?

Some organelles found only in bacteria include plasmids (extra-chromosomal DNA), carboxysomes (protein-coated organelles for CO2 fixation), and magnetosomes (membrane-bound organelles for orientation sensing).


What are the uses of protein in your body?

to synthesize new protoplasm, for growth and repair of worn-out body cells.to synthesize enzymes and some hormones.and the formation of antibodies to combat diseases.


How are transgenic organisms useful in medicine and agriculture?

Transgenic organisms could be used to make a new type of protein. For example, give a bacteria a new gene. The bacteria can then make the protein coded by the new gene. The protein may end being something such as human insulin or some other protein the bacteria don't normally produce. Your welcome Habs 13


Do bacteriophages multiply and how?

They do multiply and it's accomplished by injecting DNA into a host cell (bacteria in this case) and forcing the cell to synthesize the virus DNA, effectively creating more bacteriophages with the bacteria's own protein. The bacteria eventually bursts and the new bacteriophages are released to live happily ever after.


Describe the use of plasmids as vectors in biotechnology?

Plasmids are often used as expression vectors in biotechnology. Plasmids are small, circular or linear pieces of DNA containing non-essential genes that are found in all life, although much more common in prokaryotes, especially bacteria. These genes confer abilities such as metabolizing a previously unusable compound, building an amino acid previously unbuildable, or even antibiotic resistance. Plasmids are used in research to induce the expression of a gene usually not found in the given organism. For example, you can construct a plasmid with a bacterial promoter connected to the gene for a human protein through a process called 'cloning'. The plasmid with the human gene can then be introduced into bacteria by transforming a competent gram-negative with the plasmid. Usually the plasmid also has an antibiotic resistance gene in addition to the target gene. This antibiotic resistance can be used to select for bacteria containing the plasmid. For example, the most common resistance gene is ampicillin resistance gene. If you grow the transformed bacteria in a culture containing ampicillin, only bacteria containing the antibiotic resistance, and therefore containing the plasmid, can survive. This will ensure that what you have is a pure culture of bacteria containing the plasmid. After selection, these bacteria can be cultured in suitable media to increase their numbers to a point that their production of the human protein becomes appreciable. Then these bacteria are usually lysed (killed) to extract the protein. Sometimes, however, these bacteria can also be made to secrete the protein into the medium.
