Incorporation and expression of a plasmid in eukaryotic cells is typically achieved through a process called transfection. This involves introducing the plasmid DNA into the cells using methods such as electroporation or lipid-mediated transfection. Once inside the cell, the plasmid can be expressed by the cell's machinery to produce the desired protein or gene product.

How can plasmid linearization be achieved for optimal gene insertion and expression in molecular biology experiments?

Plasmid linearization can be achieved by using restriction enzymes to cut the plasmid at specific sites. This creates linear DNA fragments that are more easily inserted into the target gene. Linearized plasmids are preferred for gene insertion and expression in molecular biology experiments because they can integrate more efficiently into the host genome and lead to higher levels of gene expression.


Is the plasmid found in prokaryotic or eukaryotic cells?

The plasmid is found in prokaryotic cells.


Bacteria containing a plasmid into which the eukaryotic gene has integrated would grow where?

The bacteria containing the plasmid with the integrated eukaryotic gene would grow in a selective medium that supports the growth of bacteria carrying the plasmid. This medium would typically contain an antibiotic or a specific nutrient that selects for bacteria with the plasmid.


What is the origin of replication in an expression plasmid?

The origin of replication in an expression plasmid is a specific DNA sequence that allows the plasmid to replicate, or make copies of itself, within a host cell. This sequence is essential for the plasmid to be maintained and passed on to daughter cells during cell division.


How can a plasmid be engineered to include a piece of foreign DNA?

A plasmid can be engineered to include a piece of foreign DNA by using restriction enzymes to cut both the plasmid and the foreign DNA at specific sites. The two fragments are then ligated together using DNA ligase. The resulting recombinant plasmid can be introduced into a host organism for replication and expression of the foreign DNA.

What is a multicopy plasmid?

Every plasmid has a copy number that reflects the average number of copies of a certain plasmid inside a host cell(usually a bacterial cell). So a multicopy plasmid, exist in multiple copies in any given bacteria. It is believed that the higher the copy number is, the more efficient the plasmid is at replicating itself.


Why is your plasmid considered recombinant DN?

A plasmid is considered recombinant DNA when it contains DNA sequences from multiple sources that have been artificially joined together using molecular cloning techniques. This can include the insertion of a gene of interest into the plasmid for expression in a host organism, or the addition of regulatory elements to control gene expression.


You have propagated a vector in a non expression host and isolated the plasmid How can you confirm whether the plasmid that you got is exactly the vector which you propagated?

Check the size in agarose gel, extract it from the gel then purify it and grow it on selective plate.

Bacterial cells which have been transformed with a plasmid are allowed to grow so that they the plasmids everytime they divide?

The transformed bacterial cells will replicate the plasmid along with their own genomic DNA each time they divide. This allows for amplification of the plasmid within the bacterial population. The plasmid can carry genes for antibiotic resistance, gene expression, or other functions that can be advantageous for the bacteria in certain conditions.


How can large quantities of protein be produced from a bacterial colony containing the gene of interest?

Large quantities of protein can be produced by expressing the gene of interest in a bacterial colony such as E. coli. This is typically achieved by cloning the gene into a plasmid, transforming the plasmid into the bacterial cells, and inducing protein expression. The bacterial colony can then be grown in a culture medium optimized for protein production to maximize yields.


Is a plasmid a cloning vector?

Yes, a plasmid can be used as a cloning vector. Plasmids are small, circular DNA molecules that can replicate independently in a host cell. They can carry foreign DNA fragments and be used to introduce these fragments into host cells for gene cloning and expression.


What hormone directly activated vir gene in agrobacterium Ti plasmid?

The hormone that directly activates the vir gene in Agrobacterium Ti plasmid is acetosyringone. It induces the expression of the vir genes, triggering the transfer of T-DNA from Agrobacterium to plant cells.
