Genetic Engineering and Natural Selection

The video provides a comparison between natural selection and genetic engineering. It explains natural selection as a process where organisms with favorable traits survive and reproduce, using examples like the evolution of corn from teosinte. Genetic engineering is described as the deliberate modification of an organism's genetic material, with examples such as creating organisms with specific traits like red pigment. The video highlights the differences and applications of both processes.

What is the primary focus of natural selection?

• Random selection

• Phenotype-based selection

• Genotype-based selection

• Artificial selection

In the example of moths, which trait is being selected for?

• Ability to camouflage

• Color of the wings

• Size of the wings

• Speed of flight

What is the ancestor of modern corn?

• Rice

• Teosinte

• Barley

• Wheat

How has modern corn been developed from its ancestor?

• Through natural selection and cultivation

• Through genetic engineering

• Through cross-breeding with other plants

• Through chemical treatments

What is genetic engineering primarily concerned with?

• Improving natural selection

• Changing the environment

• Altering the genetic material

• Modifying the phenotype

Which of the following is a universal code that genetic engineering utilizes?

• RNA

• Proteins

• DNA

• Lipids

What can be achieved by inserting a red pigment gene into an organism?

• The organism will become more intelligent

• The organism will become larger

• The organism will grow faster

• The organism will become red

Which organism was mentioned as being genetically modified to glow?

• Clovers

• Bananas

• Mice

• Frogs

What is a key difference between natural selection and genetic engineering?

• Genetic engineering is a deliberate process

• Natural selection requires human intervention

• Natural selection is faster

• Genetic engineering is based on phenotype

What is the purpose of genetic engineering in agriculture?

• To increase crop diversity

• To enhance specific traits

• To reduce the need for water

• To eliminate pests
