Biotechnology and Molecular Life Sciences for Success

Explore how restriction enzymes cut specific DNA sequences, generating sticky or blunt ends, and how DNA ligase seals the fragments to create recombinant DNA in plasmids.

Discover how plasmid vectors ferry foreign DNA into cells, featuring origin of replication, selectable markers, and MCs. Compare cloning and expression vectors and note size limits.

Learn how PCR copies tiny DNA into millions of copies through denaturation, annealing, and extension with primers and Taq polymerase.

Learn how DNA sequencing reads the four bases, from Sanger chain-termination and capillary electrophoresis to next-generation sequencing by synthesis and nanopore third-generation methods.

Discover how to transfer recombinant DNA into cells using chemical transformation, electroporation, lipofection, gene gun, and microinjection, and compare transient versus stable transfection in different organisms.

Bioprocess engineering scales fermentation from small labs to a large bioreactor, balancing heat transfer and oxygen, with upstream and downstream processing and batch, fed-batch, and chemostat strategies.

Learn upstream processing from vial to final 500 liter reactor, focusing on biomass growth, growth medium balance, scale-up, and design of experiments to optimize yield.

Launch downstream processing by isolating a target protein from a messy fermentation broth through centrifugation or filtration, disrupt cells if needed, concentrate, and purify via chromatography before polishing and lyophilization.

Advance metabolic engineering by identifying bottlenecks with mathematical models, then overexpress key enzymes or introduce new pathways to produce biofuels, plastics, and specialized chemicals.

Explore how biotechnology converts corn, sugarcane, wood chips, and algae into liquid fuels across four generations, from ethanol in first-generation biofuels to drop-in fuels in fourth generation.

Discover how genetic modification gives crops built-in pest defenses, such as bt crops and cry proteins, reduces chemical sprays, boosts yields, and advances RNA interference–based pest control.

Boost nutrition through plant biotech with biofortification, producing beta carotene in rice, ferritin for iron, and improved amino acids, while reducing anti-nutrients and toxins for safer, more bioavailable foods.

Apply bioremediation to use bacteria, fungi, and plants to clean polluted soil and water by transforming toxins into harmless products like water and carbon dioxide, in situ or ex-situ.

Explore how biosensors combine a bioreceptor with a transducer to detect pollutants, pathogens, or sugars and convert the signal into electrochemical or optical outputs for real-time environmental and industrial monitoring.

Molecular breeding speeds trait improvement by using DNA markers and marker-assisted selection to screen thousands of seedlings, map quantitative traits (QTL), and advance crops through backcrossing, pyramiding, and genomic selection.

Describe how monoclonal antibodies, lab made identical clones produced by hybridoma technology, target cancer cells, enable diagnostics like pregnancy tests and Covid tests, and purify proteins via affinity chromatography.

Insert human genes into host cells like bacteria or chinese hamster ovary cells to produce pure human proteins, including insulin, human growth hormone, and erythropoietin, while managing folding and modifications.

Learn how gene therapy uses DNA to treat disease by replacing or inactivating genes, via in vivo and ex vivo with viral and non-viral methods, and somatic versus germline ethics.

Discover how stem cells—totipotent, pluripotent, and multipotent—and iPSCs power tissue repair, disease models, and regenerative medicine with scaffolds and three-dimensional bioprinting.

Explore molecular diagnostics with DNA, RNA, and proteins, using real-time PCR and sequencing for early detection. Learn pharmacogenomics and liquid biopsy ctDNA as paths to personalized medicine.
