Genetic engineering is possible because
1 DNA can be visualised by electron microscope
2 DNA ligase can cut DNA at specific sites
3 Restriction endonucleases can be purified from bacteria can be used in vitro
4 We can cut DNA at all sites by endonucleases
Explanation:
The discovery of Restriction endonucleases made the way for all possibilities of Biotechnology & Genetic engineering.

Statement A : Biotechnology deals with techniques that use living organism to produce products useful for humans. Statement B : Construction of recombinant DNA involves cleaving DNA segments with endonuclease and rejoining with ligase.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
The technique of using living organisms or enzymes from organisms to produce products and processes useful to humans are called biotechnology. Recombinant DNA is made by combining DNA from two or more sources. DNA fragments are cut out of a specific position in the chromosome using restriction enzymes (also called restriction endonuclease) and then inserted into other chromosomes or DNA molecules using enzyme ligase. Both statements are correct.

The specific sequence of DNA that initiate replication of alien DNA for cloning of DNA is called as
1 Promoter
2 Origin of replication
3 Origin of combination
4 Initiator
Explanation:
In a chromosome there is a specific DNA sequence called the origin of replication, which is responsible for initiating replication. Therefore, initiate replication of alien DNA for cloning of DNA which has a specific sequence known as 'origin of replication'.
