Verified By Collegedunia

The Correct Option is A

Solution and Explanation

Primers are small, 'chemically synthesised oligonucleotides that are complementary to the sequences present at $3'$ end of the template $DNA$. They hybridise to the target $DNA$ region, one to each strand of the double helix. These primers are oriented with their ends facing each other allowing synthesis of the $DNA$ towards one another.

Notes on Biotechnology

Concepts Used:

Biotechnology

Biotechnology is a vast field of biology that involves the creation, production, and modification of useful products for human welfare using both the technology and the execution of living organisms and their components. An agricultural engineer, Karoly Ereky, coined the word "biotechnology" in 1919, achieving him the title of "Father of Biotechnology."

Principles of Biotechnology:

Among many, the two core techniques that entitled the birth of modern biotechnology are :

Genetic Engineering is one of the methods of direct modifications of an organism's genome (i.e., DNA and RNA). It requires the introduction of new genes into host species to escalate function or trait, hence altering the host organism's phenotype.
Bioprocess Engineering is one of the methods of maintaining sterile conditions to facilitate the growth of large quantities of desired microbes and other eukaryotic cells for the development of new or modified biotechnological products such as enzymes, vaccines, antibiotics, and other biotechnological products.
