What is the role of plasmids in genetic engineering?

• They are used to transfer genes between organisms

• They are used to cut DNA at specific sites

• They are responsible for DNA replication

• They provide energy for cellular processes

Which of the following best describes a plasmid?

• A large linear DNA molecule

• A small circular DNA molecule

• A protein that binds to DNA

• A type of RNA molecule

What is the main function of restriction enzymes in biotechnology?

• To replicate DNA

• To cut DNA at specific sequences

• To synthesize proteins

• To transport molecules across cell membranes

What ethical concern is associated with human cloning?

• It may lead to the extinction of certain species

• It raises questions about individuality and identity

• It can cause environmental pollution

• It is too expensive to be practical

What is a major ethical concern regarding the creation of transgenic organisms/GMOs?

• They may increase the nutritional value of food

• They could potentially negatively affect the balance of natural ecosystems

• They are more expensive to produce

• They require more water to grow
