A plasmid is a small molecule of DNA that replicate independently within the cell. A population of cells carrying a desired plasmid is called a clone.

A population of cells carrying a desired plasmid is called a?
A population of cells carrying a desired plasmid is called a transformed population.
How will you identify cells carrying the recombinant plasmid?
Cells carrying the recombinant plasmid can be identified using selection markers, such as antibiotic resistance genes, that are present on the plasmid. By exposing the cells to the corresponding antibiotic, only those with the recombinant plasmid will survive. Additionally, molecular techniques like PCR or restriction enzyme digestion can be used to confirm the presence of the desired DNA sequence in the cells.
What is a Self replicating DNA used to transmit a gene from one organism to another?
Self-replicating DNA, such as a plasmid, is used in gene transfer techniques like bacterial transformation. The gene of interest is inserted into the plasmid, which can then replicate independently within a host cell, allowing for the transfer of the gene to another organism. This method is commonly used in genetic engineering to introduce new traits or gene functions into recipient organisms.
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.
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
What is found in only prokaryotic cells?

How does a human insulin genes become part of a plasmid?
Human insulin genes can be inserted into a plasmid using recombinant DNA technology. This involves isolating the insulin gene from human cells, cutting the plasmid with a restriction enzyme, and then ligating the insulin gene into the plasmid. The plasmid can then be introduced into bacterial cells for replication and production of insulin.
What enzyme is produced by cells transformed with plasmid lux that is not produced by cells transformed with pUC18?
The enzyme produced by cells transformed with plasmid lux that is not produced by cells transformed with pUC18 is luciferase. This enzyme is responsible for the bioluminescent properties of animals like fireflies and glowworms. Cells transformed with plasmid lux will emit light in the presence of the substrate luciferin, whereas cells transformed with pUC18 will not.
Why must a genetically engineered plasmid contain a genetic marker?
A genetic marker is essential in a genetically engineered plasmid to identify and select for cells that have successfully taken up the plasmid after transformation. It allows researchers to differentiate between cells that have incorporated the desired genetic material and those that have not. This marker helps ensure that only cells with the intended genetic modification are selected for further study or experimentation.
What is a plasmid exchange?
A plasmid exchange is a process where plasmids, small DNA molecules found in bacteria, are transferred between bacterial cells. This exchange can occur naturally through mechanisms like conjugation or artificially in a laboratory setting to introduce specific genes into a bacterial population. Plasmid exchange is commonly used in genetic engineering and biotechnology research.
What is recombinant Ti plasmid used for?
Recombinant Ti plasmids are used in genetic engineering to introduce foreign DNA into plant cells. This is done by Agrobacterium-mediated transformation, where the Ti plasmid delivers the desired DNA into the plant genome, allowing for the expression of novel traits or genes in the plant.
What is the function of the Ti plasmid?
The Ti plasmid is a circular DNA molecule found in Agrobacterium species. It serves as a vector for transferring genes into plant cells, leading to the formation of crown gall tumors. The transferred genes help the bacterium infect and genetically modify the plant cells to its advantage.
