Q.
Which of the following enzymes is used in genetic engineering?
Biotechnology : Principles and Processes
Solution:
Restriction endonuclease has a wide use in genetic
engineering. DNA molecules are broken down to smaller
segments by means of restriction endonucleases. They break
DNA at specific sites called restriction sites. The enzymes are
obtained from bacteria such as EcoRI from Escherichia coli,
BamHl from Bacillus amyloliquefaciens.
