Understanding CRISPR and Genetics

Front

What is CRISPR?

Back

CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a technology that allows for precise editing of DNA in organisms.

Front

What is the function of Cas9 in the CRISPR system?

Back

Cas9 is an enzyme that cuts DNA at a specific location, allowing for the addition or removal of genetic material.

Front

How does CRISPR-Cas9 edit genes?

Back

CRISPR-Cas9 edits genes by creating a double-strand break in the DNA, which the cell then repairs, allowing for the insertion or deletion of DNA sequences.

Front

What is guide RNA (gRNA)?

Back

Guide RNA is a short synthetic RNA that directs the Cas9 enzyme to the specific location in the DNA that needs to be edited.

Front

What is gene therapy?

Back

Gene therapy is a technique that modifies a person's genes to treat or prevent disease, often using technologies like CRISPR.

Front

What are the potential applications of CRISPR technology?

Back

CRISPR technology can be used in medicine, agriculture, and biological research, including gene editing for disease resistance and genetic disorders.

Front

What is a mutant gene?

Back

A mutant gene is a gene that has undergone a mutation, resulting in a change in its sequence that can affect its function.

Front

What is DNA sequencing?

Back

DNA sequencing is the process of determining the exact sequence of nucleotides in a DNA molecule.

Front

How can CRISPR be used to correct genetic disorders?

Back

CRISPR can correct genetic disorders by replacing faulty genes with healthy ones or repairing mutations.

Front

What is the significance of identifying genes affecting disease risk?

Back

Identifying genes affecting disease risk helps in understanding genetic predispositions to diseases and developing targeted treatments.
