Final answer:
Applications of rDNA technology include the production of human insulin by bacteria, the development of transgenic crops with improved traits, and the use of PCR for DNA amplification in genetic analysis.
Step-by-step explanation:
The examples of rDNA technology applications include insulin production, transgenic crops, and the use of PCR. Insulin production through recombinant DNA technology involves the insertion of the human insulin gene into a bacterial plasmid, enabling bacteria to produce insulin. This is essential for treating diabetes, as recombinant insulin is more effective for human use than animal insulin.
Transgenic crops are another application of rDNA technology, where genes from different species are inserted into plant genomes to create crops with desirable traits, such as increased yield or pest resistance.
The Polymerase Chain Reaction (PCR) is a technique used in genetic testing and research that allows for the amplification of DNA sequences, enabling detailed analysis and study of genetic material.
