The transformants are selected for on agar containing an appropriate antibiotic. For example if your recombinant plasmid contains a kanamycin cassette, then only the cells containing the plasmid will grow on an agar plate containing kanamycin. PCR can then be performed on the colonies to ensure they contain your gene of interest on the plasmid.

A population of cells carrying a desired plasmid is called a?
A population of cells carrying a desired plasmid is called a transformed population.
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.
How does a human insulin genes become part of a plasmid?
1. Scientists remove plasmids, small rings of DNA, from bacterial cells. 2. An enzyme cuts open the plasmid DNA. The same enzyme removes the human insulin gene from its chromosome. 3. The human insulin gene attaches the open ends of the plasmid to form a closed ring. 4. Some bacterial cells take up the plasmids that have the insulin gene. 5. When cells reproduce, the news cells will contain copies of the engineered plasmid. The foreign gene directs the cell to produce human insulin.
Suppose you transform bacteria with a recombinant DNA plasmid and by mistake grow the transformed cells without an antibiotic . What result would you observe?
If you grow transformed bacteria containing a recombinant DNA plasmid without an antibiotic, you would likely observe that only a small proportion of the cells that successfully took up the plasmid will survive, while the majority of non-transformed cells will also grow. However, the transformed cells may not express the gene of interest or provide any selective advantage, resulting in no significant difference in growth compared to the non-transformed cells. Over time, the population would likely consist mostly of non-transformed cells, as they do not require any selective pressure to thrive.
How recombinant DNA get introduced into host cell to transform the latter?
Recombinant DNA can be introduced into a host cell through several methods, such as transformation, transfection, or electroporation. In transformation, bacterial cells take up plasmid DNA from their environment, while transfection often involves introducing DNA into eukaryotic cells using chemical agents like liposomes or calcium phosphate. Electroporation uses an electric field to temporarily permeabilize the cell membrane, allowing DNA to enter. Once inside, the recombinant DNA can integrate into the host's genome or exist as an independent plasmid, leading to the expression of the desired genes.
A population of cells carrying a desired plasmid is called a?
A population of cells carrying a desired plasmid is called a transformed population.
What do you call a population of cells carrying a desired plasmid?
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 plasmid that contains a gene for human growth hormone is and example of what?
A plasmid containing a gene for human growth hormone can be used in genetic engineering to produce recombinant human growth hormone. This plasmid can be introduced into host cells, such as bacteria, for the production of the hormone on a large scale.
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 are the requirements for recombinant DNA technology?
Requirements for recombinant DNA technology include a vector (such as a plasmid or virus) to carry the desired DNA fragment, restriction enzymes to cut the DNA at specific sites, and DNA ligase to join the DNA fragments together. Additionally, cells capable of taking up and expressing the recombinant DNA are needed, along with appropriate selection markers to identify successfully transformed cells.

Are plasmid vectors helpful?
Plasmid vectors are an invaluable genetic engineering tool for inserting recombinant DNA sequences into different organisms or cells in culture.Plasmids are essentially circular DNA constructs composed of some essential elements like:An origin of replicationA multiple cloning site which consists of restriction sites where the recombinant DNA can be insertedMarker genes (like antibiotic resistance)reporter genes to confirm a successful transformation
What is a small circular molecule of bacterial DNA that can be used to transfer DNA into a living cell?
It's called a plasmid, but it can't be used for eukaryotic cells, only prokaryotic (bacteria). It's the basis of recombinant molecular biology.
Explain how DNA technology transfer bacterial genes from cell to cell?
I think you must rethink about your question, but still I am giving the answer as I can understand that you are asking about recombinant DNA technology where bacterial DNA is used as it is a cloning vector (plasmid). In recombinant DNA technology the particular sequence of DNA that we want to replicate or want to produce in huge number, is attached either with plasmid of bacteria or a DNA of bacteriophage and thus produce the recombinant or hybrid DNA which is copied each time when the bacteria or bacteriophage multiply. In this way the hybrid DNA will be transferred from parent cell to daughter cells.
