본문내용

Restriction enzymes and DNA ligase play essential roles in DNA cloning. How is it that a bacterium that produces a restriction enzyme does not cut its own DNA? Describe some general features of restriction enzyme site. What are the three types of DNA ends that can be generated after cutting DNA with restriction enzymes? What reaction is catalyzed by DNA ligase?

DNA Cloning Methodology

Cut the cloning vector with R.E. of choice, eg Eco RI
Cut DNA of interest with same R.E. or R.E. yielding same sticky ends, e.g. Bam HI and Sau 3A
Mix the restrict
