Study Notes
Biotechnology and bioinformatics involve using microorganisms and genetic engineering to produce useful products and analyze biological data.
- Microorganisms — small organisms with diverse metabolic capabilities. Example: Prokaryotes and eukaryotes differ in cellular organization.
- Photoautotrophs — organisms that use light energy to synthesize organic molecules. Example: Cyanobacteria.
- Chemoautotrophs — organisms that use chemical oxidation for energy to synthesize organic molecules. Example: Nitrogen-fixating bacteria.
- Fermenters — vessels that maintain optimal conditions for microorganism growth and metabolite production. Example: Used for large-scale production of metabolites.
- Pathway engineering — manipulation of genetic processes to produce desired metabolites. Example: Over-expressing genes to increase yield.
- Transgenic organisms — genetically modified organisms expressing genes from another source. Example: Crops engineered to produce novel proteins.
- Bioinformatics — use of computers to analyze biological data. Example: BLAST searches to find similar sequences in databases.
