Principle: Prokaryotic Cell Produce Restriction Enzymes (type II restriction endonucleases)
that Digest or cut DNA at Specific Sequences of 4, 6, or 8 bp.
Principle: DNA can be easily placed in bacterial cells, since Modern Transformation uses antibiotic restance
marker such as tetracycline, chloramphenicol, or ampecillin resistance.
Principle: Recombination of DNA molecules can occur in a test tube.
- Digestion of DNA with certain restriction enzymes leave sticky ends.
Sticky ends can be joined together with ligase.
- Sticky ends can be created by adding poly-A to
one set of molecules and poly-T to the other. Could you use poly-G and poly-C.
- Recombinant DNA Technology allows DNA from any source to be placed in a vector
for amplification.
- Cloning and Amplification allows the purification of small fragments
of DNA from any genome and the subsequent production of large amounts of that specific DNA.
