CRISPR is a molecular tool that can act within the genome of a living organism to add, remove, or exchange a DNA sequence. In other words, it enables scientists to delete or rewrite mutations in DNA. Although CRISPR uses some of the same viral vectors as "gene therapy," which was pioneered in the 1990s, the cargo is more targeted. This precision is why CRISPR is called "gene editing" rather than "gene therapy."

CRISPR technology has evolved at a rapid pace since 2012, and there has been speculation about applications ranging from eradication of malaria to designer babies. The technology may be particularly useful in treating hereditary conditions and cancer.

Are you familiar with the key aspects of CRISPR as a technology and its potential for transforming medicine? Test yourself with this quick quiz.
