Biotechnology: Principles and Processes
Q1: What are the most essential methods in biotechnology?
Answer:
The three most important methods used in biotechnology are:
- Recombinant DNA technology (genetic engineering),
- Plant tissue culture
- Transgenic (genetically modified organisms).
Q2: Who first discovered biotechnology?
Answer:
Karl Erki, a Hungarian engineer, first introduced the phrase “biotechnology” in 1919.
Q3: What is PCR in biotechnology?
Answer:
Polymerase chain reaction (PCR) is a technique for amplifying a gene when the appropriate gene of interest is cut out using restriction enzymes. Multiple copies of the desired gene can be generated through this technique. Denaturation, annealing, and extension are the three phases of the PCR Technique.
