RELEVANT LEARNING OUTCOME:
(a) Describe the principles and procedures of these molecular techniques: Southern blotting and nucleic acid hybridisation.
State the role of restriction enzymes in overall procedure to identify gene of interest.
🕐Estimated time for this section: 15 minutes
Watch the animation (x1.5 speed) to find out more about restriction enzymes:
What are the functions of the two enzymes that restrict the growth of bacteriophage in E.coli?
What is the name given to the specific nucleotide sequences that are recognized by restriction endonucleases?
What is meant by palindromic sequence?
After digestion with restriction enzymes, how can scientists identify which DNA fragment contains the gene of interest? (relate to Southern Blotting)
Diagram on the left show how blunt ends and sticky ends are produced by different restriction enzymes
