Detailed explanation-1: -In recombinant DNA technology, the term vector is known as a plasmid or drug used to transfer foreign DNA to living cells. Vectors are used as a vehicle for delivering foreign genetic material to another cell.
Detailed explanation-2: -Small circular DNA molecules (plasmids) are removed from bacteria. These plasmids serve as vectors (molecules to carry genes of interest).
Detailed explanation-3: -Answer and Explanation: An agent that is used to transfer the DNA in genetic engineering is called vector. A vector is a DNA molecule that can carry a gene of interest and clone it in a host.
Detailed explanation-4: -The plasmid is a type of vector commonly used in recombinant DNA technology. It is a double-stranded, circular, extrachromosomal DNA that is separated from the genomic DNA present inside the bacterial cells.. Also, it has a remarkable property of self-replication inside the host cell.
Detailed explanation-5: -Plasmids play an important role in gene therapy. Recombinant DNA technology makes use of plasmids to deliver drugs such as insulin and different hormones into the body. The modified plasmids cause antibiotic resistance and are used to kill harmful bacteria in the body.
