Chapter 21, Problem 2CONQ
Summary Introduction
To review:
The restriction enzymes and their action.
Introduction:
DNA or deoxyribonucleic acid is basically the genetic material of almost all the organism, exept viruses. Recombinant DNA technology is basically a technology wherein the DNA molecules are joined together from two different species which are inserted into the host organism to generate new genetic combinations.

- Restriction endonuclease and ligase are two types of enzymes used in the process of genetic engineering, i.e., the manipulation of genes. The restriction endonuclease differs from ligase in that it breaks the DNA at ends, while ligase causes the breaks in DNA from interior joins the fragments of DNA, while ligase breaks the DNA into fragments breaks the DNA at specific points, while the ligase joins the fragments of DNA breaks the DNA apart at each nucleotide, while ligase use the pieces to translatearrow_forwardWhat normal role do restriction enzymes play in bacteria?
