Genetic Modification
Bayani Gaba-gaba
Genetic modification lets scientists do something nature never could: move a single chosen gene from one species into a completely different one. A human gene placed in a bacterium turns that bacterium into a living factory for a human protein. It is one of the most powerful, and most debated, tools in biology.
In this lesson you will define genetic modification precisely, then (for [Supplement]) follow the step-by-step process of using bacteria to make a human protein: cutting out the gene with restriction enzymes, splicing it into a plasmid with ligase, and growing the modified bacteria so they express the human gene.
Manufura
- Describe genetic modification as changing the genetic material of an organism by removing, changing or inserting individual genes
- [Supplement] Outline the process of genetic modification using bacterial production of a human protein as an example, limited to: (a) isolation of the DNA making up a human gene using restriction enzymes, forming sticky ends (b) cutting of bacterial plasmid DNA with the same restriction enzymes, forming complementary sticky ends (c) insertion of human DNA into bacterial plasmid DNA using DNA ligase to form a recombinant plasmid (d) insertion of recombinant plasmids into bacteria (specific details are not required) (e) multiplication of bacteria containing recombinant plasmids (f) expression in bacteria of the human gene to make the human protein
