Solution and Explanation
Step 1: Genetic Modification of Organisms.
- The production of insulin in genetically modified organisms (GMOs) involves inserting the human insulin gene into a host organism's DNA, usually bacteria like Escherichia coli or yeast.
Step 2: Process of Insulin Production. - Gene Isolation: The human gene responsible for producing insulin (proinsulin) is isolated. - Gene Insertion: The gene is inserted into the DNA of a bacterial plasmid (a small, circular piece of DNA). - Transformation: The recombinant plasmid is introduced into bacterial cells. - Protein Production: The genetically modified bacteria are cultured, and they begin to produce insulin. - Harvesting: The insulin is then purified from the culture medium and used for medical purposes.
Final Answer: Insulin production in GMOs involves inserting the human insulin gene into bacteria or yeast, which then produce the protein, which is later harvested and purified.

- In a sampling expedition near a peninsula, 180 dolphins from a large population of dolphins were captured and marked by tagging their dorsal fins. The tagged dolphins were then allowed to join back into the population. In a subsequent expedition, 42 dolphins were photographed from the same large population. Among these, 7 dolphins contained the tags. Assuming that the population size remains the same and that tags were not lost, the estimated population size of dolphins in the peninsula is ...........
