Why are vectors needed for replication of DNA during rDNA technology? [HOTS]
Answers
In molecular cloning, a vector is a DNA molecule used as a vehicle to artificially carry foreign genetic material into another cell, where it can be replicated and/or expressed (e.g., plasmid, cosmid, Lambda phages). A vector containing foreign DNA is termed recombinant DNA.
Vectors in genetic engineering is usually a DNA segment used as a carrier for transferring a selected DNA into living cells.
The two examples of vector are plasmid vectors and bacteriophage vector.
please mark me as brainliest..
I am also learning...
sorry if any mistake!!=)
Answer:
A DNA vector is a nucleic acid storage system that can hold an isolated DNA sequence of interest. The essential features of a vector are that it can replicate autonomously in a host species, usually bacteria, and that it can be combined with other pieces of DNA. Often, the inserted DNA fragment comes from a different organism than the vector DNA, and the fusion is called a recombinant DNA construct. Two commonly used vectors are plasmids, naturally occurring circles of DNA that act as independently replicating accessory chromosomes in bacteria, and bacteriophage or phage, a virus that can deliver its genetic cargo to bacteria.
