Genetic Engineering Concepts and Applications

The video explores genetic engineering, starting with memorable biology labs involving bacteria and jellyfish genes. It explains how bacteria can be engineered to produce insulin, a crucial hormone for diabetes treatment. The video delves into genetic engineering techniques, including the use of plasmids, restriction enzymes, and recombinant DNA. It discusses vectors like plasmids and viruses for DNA delivery, and introduces CRISPR for precise gene editing. The video concludes with applications in medicine and agriculture, and highlights ethical considerations in genetic engineering.

What is the process called when a cell takes up DNA from its environment and uses it?

• Transformation

• Translocation

• Translation

• Transcription

What is the primary role of insulin in the human body?

• To break down proteins

• To regulate glucose levels

• To transport oxygen

• To fight infections

What is a plasmid in the context of genetic engineering?

• A type of virus

• A bacterial chromosome

• An extra set of genes in bacteria

• A human cell nucleus

Which enzyme is used to cut DNA at specific sites?

• Restriction enzyme

• Polymerase

• Ligase

• Helicase

What is recombinant DNA?

• DNA that is synthesized in a lab

• DNA that is used for protein synthesis

• DNA that contains genes from different sources

• DNA that is found in the nucleus

What is a common vector used in genetic engineering?

• Plasmid

• Bacteria

• Carbohydrate

• Protein

How does CRISPR differ from restriction enzymes?

• CRISPR is a type of plasmid

• CRISPR is not used in genetic engineering

• CRISPR uses a guide RNA to target specific genes

• CRISPR can only cut at random sites

Which of the following is an application of genetic engineering in agriculture?

• Producing insulin

• Studying gene functions in mice

• Developing drought-resistant crops
