The Power of CRISPR: Unraveling the Future of Gene Editing

The video explains the role of genes and DNA in living organisms and introduces CRISPR, a gene-editing tool derived from a natural bacterial immune system. CRISPR uses Cas9 proteins to edit DNA, offering potential applications in agriculture, medicine, and research. However, ethical concerns and the unpredictability of long-term effects pose challenges.

What role do genes play in living organisms?

• They store nutrients for the cell.

• They are responsible for cellular waste removal.

• They provide energy for cellular processes.

• They act as a blueprint for cellular functions.

What is CRISPR originally known for?

• A process for photosynthesis.

• A tool for creating synthetic organisms.

• A natural bacterial immune system.

• A method for cloning animals.

What are the two main components of the natural CRISPR system?

• CRISPR sequences and Cas proteins.

• Guide RNA and Cas9 proteins.

• DNA polymerase and ribosomes.

• mRNA and tRNA.

How do scientists use CRISPR to edit genes?

• By using chemical reactions to alter DNA sequences.

• By exposing cells to high-energy radiation.

• By using a guide RNA to direct Cas9 to the target gene.

• By injecting DNA directly into the cell nucleus.

What happens to DNA after it is cut by CRISPR?

• The cell attempts to repair it, sometimes introducing errors.

• It is left unrepaired, leading to cell death.

• It is duplicated to create more copies.

• It is immediately repaired without any errors.

What is homology directed repair?

• A way to remove damaged DNA from the cell.

• A technique for increasing gene expression.

• A process that uses a template to accurately repair DNA.

• A method for duplicating DNA sequences.

Which of the following is a potential application of CRISPR?

• Generating synthetic water from air.

• Creating plants that can grow without sunlight.

• Developing drought-resistant crops.

• Producing animals that do not require food.

What is a major concern regarding the use of CRISPR technology?

• It may cause unintended genetic changes.

• It can only be used in bacteria.

• It is ineffective in altering DNA.

• It is too expensive for widespread use.

Why is it important to consider the ethical implications of CRISPR?

• Because it is a new technology with unknown long-term effects.

• Because it is only applicable to plant life.

• Because it has no impact on human health.

• Because it is a natural process with no human intervention.

What is a limitation of CRISPR technology?

• It can only edit viral DNA.

• It is not precise and can cause off-target effects.

• It requires a large amount of energy to function.

• It is only effective in laboratory settings.
