Gene Editing: Curing Genetic Diseases

What is the primary goal of gene editing as discussed in the article?

• To create new genetic mutations

• To correct mutations that cause genetic diseases

• To increase the speed of DNA replication

• To enhance the body's ability to destroy foreign molecules

What is β-thalassemia?

• A type of cancer

• A blood disorder where hemoglobin production is impaired

• A neurological disorder

• A viral infection

How many nucleotides does a cell copy per second during division?

• 10

• 50

• 100

• 1000

What is the role of nanoparticles in gene editing?

• To destroy the body's immune system

• To carry genetic editing molecules to their destination

• To increase the size of the molecules

• To replace DNA repair molecules

What is a specificity molecule used for in gene editing?

• To increase the speed of DNA replication

• To tell the editor molecule where to cut the DNA strand

• To destroy unwanted DNA

• To create new DNA strands

What is the significance of using fetal mice for genetic editing experiments?

• Fetal mice have a slower DNA replication rate

• DNA replication is fastest in fetal animals

• Fetal mice are immune to genetic mutations

• Fetal mice do not have a liver

What percentage of hemoglobin-producing cells were successfully edited in the experiment?

• 1%

• 6%

• 10%

• 50%

What is the main challenge in using gene editing to cure diseases?

• The body is very good at destroying foreign molecules

• The editor molecules are too large

• The specificity molecules are ineffective

• The nanoparticles are too big

What is the role of donor DNA in gene editing?

• To destroy the mutated gene

• To serve as a template for replacing the mutated section

• To increase the mutation rate

• To bind with the editor molecule

What is a box and whisker plot used for?

• To show the average value of a dataset

• To represent a range of data points

• To display only the maximum and minimum values

• To show the frequency of data points
