Genetic Modification Concepts and Misconceptions

The video explains genetically modified organisms (GMOs), their definition, and how they differ from traditional breeding methods. It covers the production of insulin using GMOs, various genetic modification techniques, and the distinction between transgenic and cogenic organisms. The video also discusses mutagenic breeding, cloning, and public perception of GMOs, highlighting why they are often viewed as unnatural.

What was the primary source of insulin for diabetics before the advent of recombinant human insulin?

• Human pancreas

• Genetically modified bacteria

• Pig pancreas

• Synthetic chemicals

What is the role of a plasmid in genetically modified bacteria?

• It acts as a promoter for gene expression.

• It is a loop of DNA that can replicate inside bacteria.

• It is used to extract insulin from bacteria.

• It is a type of bacteria used in genetic modification.

Which method is NOT used to introduce new genetic material into cells?

• Magnetic fields

• Tiny gold particles

• High-intensity ultrasound

• Electric shocks

What distinguishes a transgenic organism from a cogenic organism?

• Transgenic organisms contain genes from the same species.

• Cogenic organisms are not genetically modified.

• Cogenic organisms contain genes from different species.

• Transgenic organisms contain genes from different species.

Which of the following is an example of a transgenic organism?

• A cloned sheep

• A potato resistant to blight

• A glow-in-the-dark cat

• A seedless banana

What is the main advantage of cisgenic modification over traditional breeding methods?

• It introduces genes from different species.

• It is faster and more precise.

• It does not require genetic engineering.

• It produces larger plants.

What is the primary difference between mutagenic breeding and genetic modification?

• Genetic modification introduces random mutations.

• Mutagenic breeding introduces random mutations.

• Genetic modification is slower.

• Mutagenic breeding is more precise.

What is a common misconception about cloning?

• Cloning is used to create armies.

• Cloning is only possible in plants.

• Clones are genetically identical to their parents.

• Cloning involves genetic modification.

Why do some people fear GMOs?

• They sound unnatural and strange.

• They are more expensive.

• They are less effective than traditional methods.

• They are always harmful to health.

What was the public reaction to inserting a gene from an Arctic fish into a tomato?

• Curious and interested

• Visceral negative opinions

• Indifferent

• Positive and supportive
