Study Notes
Biotechnology in Medicine and Agriculture
- Transgenic organisms, like mice, produce proteins to be used in humans, and crops are modified to have desirable traits, like disease resistance.
- Transgenic plants, a type of genetically modified organism (GMO), receive DNA from different species.
- GMOs are carefully monitored to ensure they are safe for consumption and don't harm other living things.
- Plants are a major food source for humans; farmers have been selecting desirable traits in plants for a long time.
- Biotechnology techniques have enabled the creation of crops with improved nutrition, resistance to diseases and pests, and longer shelf life.
Transgenic Plants
- Genetically modified organisms (GMOs) are created by manipulating plant DNA.
- These GMOs offer desirable traits like disease resistance, pest resistance, and improved nutritional value.
- Bt toxin from the Bacillus thuringiensis bacterium is used as a natural insecticide.
- The FlavrSavr tomato, an early GMO, was created to have extended shelf life.
Genomics and Proteomics
- Genomics studies entire genomes, including genes, their sequences, and interactions.
- Whole genome sequencing provides comprehensive DNA sequence information.
- Genetic mapping identifies gene locations on chromosomes.
- Physical mapping details the physical distance between genes.
- Genome mapping helps understand disease-causing genes and develop treatments.
Whole Genome Sequencing
- Whole genome sequencing determines the complete DNA sequence of an organism's genome.
- It's used to analyze diseases with a genetic basis.
- It's used in medicine to diagnose and treat diseases.
- This process has helped in identifying a genetic basis for a medical issue that resulted in the successful treatment of a young boy.
Applying Genomics
- Genome analysis can predict an individual's risk for disease.
- Lifestyle changes and drugs can intervene before disease onset.
- Disease analysis may involve identifying single gene defects or multiple genes.
- Genomics has been applied in the medical field to develop personalized treatments and strategies for disease prediction.
Gene Editing, Pharmacogenomics, and Metagenomics
- CRISPR gene editing allows for precise alterations of DNA.
- Pharmacogenomics uses genomic information to personalize drug selection.
- Metagenomics studies the collective genomes of organisms within an environment.
- Researchers now use genomic information for various medical needs and applications.
Mitochondrial Genomics and Forensic Analysis
- Mitochondrial DNA, inherited maternally, is useful for tracing ancestry and solving crimes.
- Genomic and analysis tools have helped in solving crimes cases.
- Linking specific traits and diseases to genomic information has become useful.
Genomics in Agriculture
- Improving crop quality and quantity using genomics.
- Gene-trait linkages are used to improve crop quality.
- Genomic data is used to identify desirable plant traits and transfer them to other organisms.
- Making crops more resistant to environmental factors is an important objective.
Proteomics
- Proteomics studies the complete set of proteins in a cell or organism.
- It complements genomics and helps understand function and disease.
- Predicting disease, understanding cancer, and predicting disease recurrences are applications of this area.
- Protein signatures are a useful tool for diagnosing and treating cancer.
