Read the following text and answer the following question on the basis of the same:

The term biotechnology refers to the use of living organisms or their products to modify human health and their human environment. For example, ‘testtube’ programme, synthesis of a gene or correcting a defective gene are all part of biotechnology. The basis of modern biotechnology is genetic engineering and maintenance of sterile conditions. Genetic engineering is the technique that alter the chemistry of genetic material i.e. DNA and RNA, then this genetic material is introduced into host organisms, which alter the phenotype of the host organism.

Q. Discovery of _________ molecule made genetic engineering possible.

Q. The specific DNA sequence where EcoRI cuts is :

Read the following and answer the question given below :

Restriction endonuclease was isolated for the first time by W. Aber in 1962 in bacteria. Restriction endonucleases cut the DNA duplex at specific points therefore they are also called molecular scissors or biological scissors. Three types of restriction endonucleases are Type 1. Type ll and Type III but only Type II restriction endonucleases are used in recombinant DNA technology. Restriction endonuclease EcoR I recognises the base sequence GAATTC In DNA duplex and cut strands between G and A.

Q. Only type II restriction enzymes are used in gene manipulation because:
