Vector are plasmid DNA, act as a molecular vehicles to carry genes or DNA of interest. In rDNA technology vectors used to clone the gene by ligation. This chimeric DNA or plasmid can be propagated in E.coli as the vector carries its own origin of replication. Expression plasmid vectors can be used to produce proteins from the gene of interest.

What is the substance required to cleave the vector DNA during recombinant DNA technology?
Restriction enzymes are the substances required to cleave the vector DNA during recombinant DNA technology. These enzymes recognize specific DNA sequences and cut the DNA at specific points, allowing for the insertion of foreign DNA fragments.
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.
What is a small double stranded DNA that's used as a vector?
it is a ds DNA use in recombinant DNA technology to insert our interested gene and multiply it.Ex;plasmid,cosmid
How can one create recombinant DNA?
Recombinant DNA is created by combining DNA from different sources using enzymes called restriction enzymes. These enzymes cut the DNA at specific points, allowing the desired DNA fragments to be inserted into a vector, such as a plasmid. The vector is then introduced into a host cell, where it replicates and produces the desired recombinant DNA.
What are the recombinant DNA is formed by joining DNA molecules?
Recombinant DNA is formed by joining DNA molecules from different sources using enzymes, such as restriction enzymes and DNA ligase, to cut and connect the DNA sequences. This process allows for the creation of new combinations of genetic material that may not naturally occur. Recombinant DNA technology is widely used in genetic engineering and biotechnology for various applications.
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.
What carries recombinant dna into bacteria?
A common method to introduce recombinant DNA into bacteria is through a process called transformation. In this process, bacteria are made competent to take up foreign DNA, usually through chemical treatment or electroporation. Once inside the bacteria, the recombinant DNA can replicate and be expressed.
Explain the role of klenow fragment in recombinant DNA technology?
The Klenow fragment, derived from the DNA polymerase I enzyme, is used in recombinant DNA technology to fill in the single-stranded DNA gaps left in a vector after annealing with a DNA insert. It possesses 5' to 3' polymerase activity and 3' to 5' exonuclease activity, allowing it to extend the DNA strands in a template-directed manner. This helps to create recombinant DNA molecules with high efficiency.
Describe one similarity between PCR and recombinant DNA technology.?
PCR is the abbreviation for polymerase chain reaction. It is similar to recombinant DNA technology in that both have the ability to sequence DNA.
Where does new DNA come from in gene cloning?
New DNA molecules can come from various sources in gene cloning, such as PCR amplification of a specific gene, synthesis of a gene using recombinant DNA technology, or isolation of a gene from a donor organism. These DNA molecules are then inserted into a vector, such as a plasmid, to create a recombinant DNA molecule for cloning.
Why cleavage of DNA is done in recombinant DNA technology?
Recombinant DNA technology is the most emerging technique for the production of DNA for the useful bio-materials like insulin. So to produce recombinant DNA two different DNA is rejoined. so cleavage is done to extract the desired DNA and then joined again.
What is the Significance of host cell in recombinant DNA technology?
The host cell is important in recombinant DNA technology because it is the organism that will replicate the recombinant DNA construct. The DNA construct is inserted into the host cell, which then uses its machinery to produce the desired protein or molecule encoded by the inserted DNA. The choice of host cell is critical as it can affect the efficiency of DNA replication, protein production, and post-translational modifications.
