Isolating the desired DNA fragment using restriction enzymes
a. is a carbon copy of an individual. It is a process of creating a genetically identical copy of an organism.
b. involves inserting a gene or a DNA fragment into a bacterial cell, which then multiplies (copies) the DNA when the cell divides. The basic steps involved in gene cloning is outlined below:
Step \(1\):
Step \(2\):
Step \(3\):
Step \(4\):
Step \(5\):
c. The first recombinant DNA was constructed by and in the year \(1972\).
d. A piece of DNA from a plasmid carrying antibiotic resistance gene in the bacterium was cut with the help of .
