You could mention second messenger of ATP in control of blood glucose - cAMP.
•
The ATPPC system - an anaerobic system used for energy in muscle contraction - ADP + PCr -> ATP + Cr
•
don't forget the Na+ K+ pump in maintaining resting potential
•
A Restriction endonuclease is used to isolate the fragment by it cutting at recognition sites either side of the fragment - sticky ends are left.
•
A plasmid is used as a vector and is cut with the same restriction enzyme that was used to isolate the fragment. The fragment is then mixed with the plasmid and due to the sticky ends the fragment fits in with the help of DNA Ligase which joins the sticky ends
•
The vector then inserts the gene into a host cell, some techniques are used to increase chance of uptake (e.g. CaCl2 and/or heat shocking)
•
Transformed host cells are then identified either by the older method of using replica plating to identify with antibiotic resistance or nowadays the use of fluorescent labels are used (the marker genes for this is added to the vector during that stage)
