Study Notes
Genetic Engineering Definition
- Genetic engineering is the direct, deliberate alteration of an organism's genome.
Golden Rice
- Vitamin A deficiency causes blindness and infant mortality, especially in impoverished nations.
- An estimated 500,000 children go blind annually due to vitamin A deficiency.
- Golden rice was developed by inserting the gene for vitamin A (beta-carotene) into rice.
- The added vitamin A gives the rice a golden color.
Genetic Engineering Process Overview
- Gene Isolation: Extract the desired gene from the donor organism's genome.
- Gene Insertion Vector: Attach the gene to a plasmid (a small, circular DNA molecule).
- Transformation: Introduce the plasmid containing the gene into the target organism (host cell).
Green Fluorescent Protein (GFP)
- A jellyfish protein that makes the jellyfish glow under certain light.
- GFP is a useful biological tool.
- By linking GFP to other proteins, scientists can visualize those proteins within cells.
- This allows studies on cancer cell spread, proteins associated with cystic fibrosis, and developmental processes in various species.
Genetic Engineering Lab Example
- Genetic Donor: Jellyfish (for GFP).
- Genetic Host: Bacteria (e.g., E. coli).
