Study Notes
DNA Technology and Genomics
- DNA technology is important for forensics, producing medical/industrial products, investigating evolutionary relationships, and biological research.
- Biotechnology involves manipulating organisms to make useful products. DNA technology uses modern techniques to manipulate genetic material.
- Gene cloning produces identical copies of a gene. Recombinant DNA is formed by joining nucleotide sequences from different sources.
- Plasmids, phages, and BACs are used to construct genomic libraries. A cDNA library is different from a genomic library.
- Restriction enzymes cut DNA at specific sequences, creating sticky ends for joining with other fragments.
- DNA ligase joins DNA fragments together.
- Nucleic acid probes identify specific genes in libraries.
- Genetically modified organisms (GMOs) are used to mass-produce proteins.
- Bacteria, yeast, and mammalian cells are used for mass production of proteins.
- GMOs transform agriculture by creating crops resistant to herbicides and pests.
- Benefits include increased nutrition and disease resistance in plants. Risks need safeguarding against pathogens.
- DNA profiling analyzes genetic markers to determine if DNA comes from the same individual.
- Polymerase Chain Reaction (PCR) rapidly amplifies DNA sequences.
- Gel electrophoresis separates DNA and proteins by size and charge.
