Final answer:
Recombinant DNA technology is applied in insulin production and the creation of transgenic crops. CRISPR is a gene-editing tool, and PCR is a DNA amplification method, neither of which involves combining DNA from different sources like rDNA technology does. Correct options are a,b.
Step-by-step explanation:
The examples of rDNA technology applications that are correct are insulin production and transgenic crops. Insulin production through rDNA technology involves creating bacteria that carry the human gene for insulin, allowing for the production of insulin that is identical to naturally produced insulin.
This is crucial for treating diabetes, as it provides a synthetic version of human insulin, avoiding the potential for allergic reactions that might occur with animal-derived insulin. Transgenic crops are another application, where genes are inserted into crops to enhance desirable traits such as yield or pest resistance, creating genetically modified organisms that can benefit agriculture.
CRISPR and PCR are not examples of rDNA technology. CRISPR is a gene-editing technology that allows for the precise modification of DNA within organisms. PCR, or polymerase chain reaction, is a technique used to amplify small segments of DNA, creating millions of copies for analysis, rather than the recombination of genetic material from different sources.
In conclusion, the correct options related to rDNA technology applications are a. Insulin production and b. Transgenic crops.
