Why is PCR of an utmost importance in genetics research?
The high sensitivity and specificity of RT-PCR makes it a particularly useful and powerful technique for monitoring the mRNA expression of pathogen genes during host infection, where the pathogen’s expression profile is often masked by the much higher concentration of host RNA.
What is the importance of PCR test?
PCR tests can detect disease when there is only a very small amount of pathogens in your body. During a PCR test, a small amount of genetic material in a sample is copied multiple times. The copying process is known as amplification. If there are pathogens in the sample, amplification will make them much easier to see.
What are the advantages of cloning Class 8?
- Production of exactly identical copies of animals.
- In domestic animals, superior milk yielding cows are cloned.
- Sheep that yields high and superior quality wool are cloned to produce sheep that give a high yield of superior quality as well.

What is disadvantage of cloning?
The disadvantage of cloning animals is that prolonged use of this technology would create a genetic bottleneck. With all animals have nearly the same, if not identical, genetic makeup, the species would be at an increased risk of extinction because of the risks of inbreeding.
What are the advantages and disadvantages of recombinant DNA technology?
Recombinant DNA technology, also called “genetic engineering,” has many benefits, such as the ability to improve health and improve the quality of food. But there are downsides as well, such as the potential for using personal genetic information without consent.
What is the use of PCR in recombinant DNA technology?
The Polymerase Chain Reaction (PCR) is used to amplify specific regions of a DNA strand millions of times. A region may be a number of loci, a single gene, a part of a gene, or a non-coding sequence. This technique produces a useful quantity of DNA for analysis, be it medical, forensic or some other form of analysis.
What is the importance of recombinant DNA technology?
Recombinant DNA technology has also proven important to the production of vaccines and protein therapies such as human insulin, interferon and human growth hormone. It is also used to produce clotting factors for treating haemophilia and in the development of gene therapy.
