WHAT IS A VECTOR IN BIOTECHNOLOGY?
Biotechnology is divided into two words- biology and technology which means we use different techniques to improve our health and environment.
How can we use these techniques??? Answer to this in biotechnology is genetically manipulating microorganisms and for genetically manipulation of microorganisms we need a vector.
Thus, vector is a DNA molecule which is used as a vehicle that carry foreign genetic material which is artificially prepared into another cell. And in another cell it can be replicated or expressed. Vector that contains foreign DNA is called recombinant DNA.
HOW VECTORS USED IN BIOTECHNOLOGY :
For cloning vector to be maintained in an organism, it must some features. Vectors must have antibiotic resistant genes by which humans and animals diseases can be treated. Antibiotic resistance genes can also be used for expression of plasmid DNA.
Vectors may carry genes that are helpful for environment as they can in digest the pollutants.
Vectors must produce antibacterial proteins when they are cloned in bacteria.
