Summary and Exam Tips for Biotechnology and Bioinformatics
Biotechnology and Bioinformatics is a subtopic of Option B - Biotechnology and Bioinformatics, which falls under the subject Biology in the IB DP curriculum. This field explores the use of microorganisms in industry due to their metabolic diversity and rapid growth rates. Microorganisms can be classified based on their cellular organization, nutritional requirements, and respiration methods. Industrial biotechnology leverages these traits for large-scale production using fermenters, which facilitate the growth of microorganisms under optimal conditions. Pathway engineering is employed to enhance metabolite production, while biogas production utilizes bacteria and archaeans to convert organic matter into energy. In agriculture, transgenic organisms are created through genetic modification to express novel proteins, with recombinant DNA being introduced into plants for targeted genetic transformation. Bioinformatics plays a crucial role in identifying target genes using databases and tools like BLAST for sequence alignment. Bioremediation uses microorganisms to degrade pollutants, while biofilms exhibit emergent properties such as increased resistance to antimicrobials. In medicine, biopharming uses genetically modified organisms to produce therapeutic proteins, and DNA microarrays help detect genetic predispositions to diseases.
