Class 12 NEET Biology Biotechnology Principles and Processes

DNA fragments generated by the restriction endonucleases in a chemical reaction can be separated by electrophoresis. The polymerase chain reaction is simply DNA replication in a test tube. Restriction mapping is the process of obtaining structural information on a piece of DNA by the use of restriction enzymes, e.g., endonucleases that recognise specific 4 to 8 base regions of DNA
