How does the guide RNA help the cell know where to cut the DNA?

• Guide RNA helps to find the PAM

• Guide RNA is complementary to the DNA sequence

• Guide RNA always binds to the same sequence of DNA

• Like restriction sites, they are always palindromes

CRISPR can change DNA in humans and animals.  What did scientists look at to help them create CRISPR?

(cosa hanno dovuto osservare gli scienziati per aiutarli nella creazione del CRISPR?)

• Sheep cloning

• Palindromic repeats

• Common Cold

• Bacteria fighting off viruses

• Replicase

• Lysozyme

• Cas9

Which of the following best describes the process of gene editing?

• Removing, adding, or altering genetic material at particular locations in the genome

• Changing the entire genome of an organism at once

• Selectively breeding organisms to promote desired traits

• Introducing foreign DNA into an organism's genome without specificity

1. A team of neuroscientists is using CRISPR technology to study a rare neurological disorder in mice. They introduce a mutation into a specific gene suspected to cause the disorder and observe its effects.

3. Part 2: How can this mouse model benefit the neuroscientists' research?

• By providing insights into the genetic basis and potential treatments for the disorder

• By offering a way to reduce interest in the research

• By preventing the disorder from manifesting in the mice

• By creating more complex disorders unrelated to the research

What do scientists use the CRISPR/Cas9 tool for?

• To create new people.

• To alter an organism's protein.

• To alter an organism's genome.

• To fight off viruses in RNA.

What is the main purpose of using CRISPR-Cas9 in agriculture?

• To increase the size of the fruits and vegetables

• To create plants that are resistant to diseases and pests

• To reduce the time it takes for crops to mature

• To change the color of the crops

Part 1: What is the goal of using CRISPR to introduce this mutation in mice?

• To disrupt the mice's ability to learn

• To create a model for studying the disorder's progression and symptoms

• To eliminate all genes associated with the disorder

• To increase the mice's lifespan

A medical research team is working on developing a new treatment for a genetic disease by targeting and editing the mutated gene responsible for the condition. They use CRISPR-Cas9 technology to accomplish this goal. What is the primary advantage of using CRISPR-Cas9 in this scenario?

•  It can only target one specific gene.

• It randomly modifies multiple genes at once.

•  It can precisely target and edit specific genes with high accuracy.

• It eliminates the need for DNA analysis.
