Exploring Genetic Engineering

What is the primary purpose of gene cloning techniques?

• To analyze the function of proteins in a cell.

• To enhance the expression of all genes in an organism.

• To create copies of specific genes or DNA sequences.

• To eliminate unwanted genes from a DNA sequence.

Name one common method used in gene cloning.

• DNA sequencing

• Gel electrophoresis

• Restriction enzyme digestion

• PCR amplification

What ethical concerns are associated with genetic engineering?

• Ethical concerns include unintended consequences, social inequality, consent issues, moral status of modified organisms, and impacts on biodiversity.

• Genetic engineering eliminates all diseases.

• All genetic modifications are reversible.

• Genetic engineering has no impact on the environment.

How does genetic engineering impact biodiversity?

• Genetic engineering solely benefits native species without any negative impact.

• Genetic engineering increases biodiversity by enhancing species variety.

• Genetic engineering has no effect on biodiversity whatsoever.

• Genetic engineering can reduce biodiversity by promoting monocultures and displacing native species.

What is a genetically modified organism (GMO)?

• An organism that has been bred through traditional methods.

• A species that has undergone natural selection.

• An organism that has been frozen for preservation.

• A genetically modified organism (GMO) is an organism whose genetic material has been altered using genetic engineering.

List one application of genetic engineering in agriculture.

• Wheat that is engineered for higher gluten content.

• Bt cotton, which is engineered to be resistant to certain pests.

• Rice that is designed to have a longer shelf life.

• Genetically modified tomatoes that grow faster.

What is the role of CRISPR in gene editing?

• CRISPR is a type of antibiotic used in medicine.

• CRISPR can only edit RNA sequences.

• CRISPR is used to clone entire organisms.

• CRISPR enables precise gene editing by using guide RNA and the Cas9 enzyme to target and modify specific DNA sequences.

Describe one approach to gene therapy.

• Using CRISPR to cut out defective genes without replacing them.

• Administering antibiotics to prevent gene expression errors.

• Using viral vectors to deliver healthy genes to replace defective ones.

• Injecting proteins directly into cells to enhance gene function.

What are the potential risks of gene therapy?

• Potential risks of gene therapy include immune reactions, insertional mutagenesis, off-target effects, and unknown long-term consequences.

• Gene therapy has been proven to be completely safe for all patients.

• Gene therapy is always successful without any risks.

• Gene therapy only affects the targeted cells without any side effects.

How can genetic engineering improve crop resistance?

• Genetic engineering reduces the need for fertilizers and pesticides.

• Genetic engineering improves crop resistance by introducing genes that enhance resistance to pests, diseases, and environmental stresses.

• Genetic engineering solely focuses on increasing crop yield without considering resistance.

• Genetic engineering eliminates all environmental stresses on crops.
