Understanding Gene Cloning

What is gene cloning?

• Gene cloning is the process of creating identical copies of a specific gene or DNA sequence.

• Gene cloning is the process of altering a gene's function.

• Gene cloning involves the random mixing of DNA sequences.

• Gene cloning is the method of deleting genes from an organism.

Why is gene cloning important in science?

• Gene cloning is important for research, medical advancements, and agricultural improvements.

• Gene cloning has no impact on food production.

• Gene cloning is primarily used for entertainment purposes.

• Gene cloning is only useful for creating pets.

What are the basic steps involved in gene cloning?

• The basic steps involved in gene cloning are isolation, insertion, transformation, selection, and verification.

• Extraction, amplification, sequencing, analysis, storage

• Isolation, sequencing, transformation, analysis, storage

• Replication, modification, extraction, analysis, verification

What is a vector in gene cloning?

• A vector is a DNA molecule used to carry foreign genetic material into a host cell in gene cloning.

• A vector is a type of cell used to store DNA samples.

• A vector is a method for analyzing genetic sequences.

• A vector is a type of protein used in gene cloning.

How do scientists insert a gene into a vector?

• Synthesizing the gene without a vector

• Using a virus to randomly insert the gene

• Scientists insert a gene into a vector by isolating the gene, cutting the vector with restriction enzymes, ligating the gene into the vector, and introducing the vector into host cells.

• Injecting the gene directly into the host cell

What role do restriction enzymes play in gene cloning?

• Restriction enzymes cut DNA to create compatible ends for gene cloning.

• Restriction enzymes amplify DNA sequences for cloning.

• Restriction enzymes synthesize RNA from DNA templates.

• Restriction enzymes are used to insert plasmids into bacteria.

What is the purpose of using a host organism in gene cloning?

• To eliminate the need for DNA extraction.

• To replicate and express the cloned gene.

• To enhance the host's immune response.

• To create a new species of organism.

Can gene cloning be used in medicine? Give an example.

• Yes, gene cloning can be used in medicine. An example is the production of insulin for diabetes treatment.

• Gene cloning is illegal in all countries.

• Gene cloning can create new species of animals.

• Gene cloning is only used in agriculture.

What ethical concerns are associated with gene cloning?

• Cloning is a guaranteed way to create superhumans

• Gene cloning has no impact on biodiversity

• Gene cloning eliminates all diseases

• Ethical concerns include genetic discrimination, 'playing God', reduced genetic diversity, moral status of clones, consent issues, and unforeseen consequences.

How has gene cloning impacted agriculture?

• Gene cloning has decreased the variety of crops available.

• Gene cloning has significantly improved crop yields, pest resistance, and nutritional quality in agriculture.

• Gene cloning has no effect on agricultural practices.

• Gene cloning has led to increased pesticide use in farming.
