Genetically Modified Organisms (GMOs) and Climate Change

Front

What is a genetically modified organism (GMO)?

Back

A GMO is an organism whose DNA has been altered through genetic engineering.

Front

What are some examples of GMOs mentioned in the text?

Back

Examples include purple tomatoes, white strawberries, Bt corn, and golden rice.

Front

What are the benefits of modifying an organism's DNA?

Back

Benefits include increased food availability, quality, and environmental cleanliness.

Front

What is biological nitrogen fixation (BNF)?

Back

BNF is the process of converting atmospheric nitrogen into a usable form for crops.

Front

How do GMOs differ from selective breeding?

Back

GMOs are created through direct DNA modification, while selective breeding enhances traits over generations without altering DNA.

Front

What is the process for creating a GMO?

Back

1. Identify the desired trait. 2. Copy the gene. 3. Insert the gene into another organism's DNA. 4. Grow the new organism.

Front

What are some safety concerns surrounding GMOs?

Back

Concerns include potential allergens, transfer of antibiotic resistance, and unknown effects on health and the environment.

Front

What ethical issues are associated with GMOs?

Back

Ethical issues include tampering with nature, mixing genes among species, and objections to transferring animal genes into plants.

Front

What is the role of the National Committee on Biosafety of the Philippines?

Back

It oversees compliance with biosafety policies and guidelines in genetic engineering experiments.

Front

What is the significance of Bt corn?

Back

Bt corn is genetically engineered to produce insecticidal proteins to resist pests like the Asian corn borer.
