-
Genetic engineering
- Involves the direct manipulation of an organism's DNA to alter its characteristics.
- Techniques include gene cloning, gene editing, and the introduction of new genes.
- Applications range from agriculture to medicine, enhancing traits or producing therapeutic proteins.
-
Recombinant DNA technology
- Combines DNA from different sources to create new genetic combinations.
- Used to produce insulin, growth hormones, and vaccines.
- Involves the use of vectors, such as plasmids, to transfer genes into host cells.
-
Polymerase Chain Reaction (PCR)
- A technique used to amplify specific DNA sequences, making millions of copies from a small sample.
- Essential for genetic testing, forensic analysis, and research applications.
- Involves cycles of denaturation, annealing, and extension to replicate DNA.
-
Gene therapy
- A method to treat or prevent disease by inserting genes into a patient's cells.
- Can correct genetic disorders by replacing faulty genes or introducing new ones.
- Still in development for many conditions, including genetic diseases and some cancers.
-
CRISPR-Cas9 gene editing
- A revolutionary tool that allows precise editing of DNA sequences in living organisms.
- Utilizes a guide RNA to direct the Cas9 enzyme to specific locations in the genome.
- Applications include disease research, agriculture, and potential therapeutic uses.
-
Biopharmaceuticals
- Medications produced using biotechnology, often derived from living organisms.
- Include monoclonal antibodies, vaccines, and recombinant proteins.
- Offer targeted therapies for diseases like cancer and autoimmune disorders.
-
Monoclonal antibodies
- Laboratory-made molecules that can mimic the immune system's ability to fight off pathogens.
- Used in diagnostics, treatment of diseases, and as targeted therapies in cancer.
- Produced by creating identical copies (clones) of a single type of immune cell.
-
Stem cell technology
- Involves the use of stem cells to regenerate or repair damaged tissues and organs.
- Can differentiate into various cell types, offering potential treatments for degenerative diseases.
- Ethical considerations and regulatory challenges are significant in this field.
-
Bioremediation
- The use of microorganisms to clean up contaminated environments, such as oil spills or heavy metal pollution.
- Harnesses natural processes to degrade pollutants into less harmful substances.
- Offers a sustainable and cost-effective approach to environmental restoration.
-
Agricultural biotechnology (GMOs)
- Involves the genetic modification of crops to enhance yield, resistance to pests, and nutritional value.
- GMOs can reduce the need for chemical pesticides and improve food security.
- Controversial due to concerns about safety, environmental impact, and ethical issues.
-
Biofuels
- Renewable energy sources derived from biological materials, such as plants and waste.
- Can reduce reliance on fossil fuels and lower greenhouse gas emissions.
- Includes ethanol, biodiesel, and biogas, produced through fermentation or other processes.
-
DNA fingerprinting
- A technique used to identify individuals based on their unique DNA profiles.
- Commonly used in forensic science, paternity testing, and genetic diversity studies.
- Relies on analyzing specific regions of DNA that vary greatly among individuals.
-
Biosensors
- Devices that detect biological molecules and convert their presence into measurable signals.
- Used in medical diagnostics, environmental monitoring, and food safety.
- Can provide rapid and accurate results for various applications.
-
Tissue engineering
- Combines biology and engineering to create artificial organs and tissues for medical use.
- Involves scaffolding, cells, and growth factors to promote tissue regeneration.
- Holds promise for transplant medicine and regenerative therapies.
-
Nanobiotechnology
- The application of nanotechnology in biological systems, enhancing drug delivery and diagnostics.
- Involves manipulating materials at the nanoscale to improve efficacy and reduce side effects.
- Potential applications include targeted cancer therapies and advanced imaging techniques.
