Genetic engineering, a method that can create more complex and even the most subtle changes to a DNA strand, can be used to cure the most common of diseases and alter their paths. CRISPR, a new and quickly improving technology, focuses on finding the root of the genetic cause of diseases like breast and ovarian cancers, diabetes, Alzheimer’s, and thousands of other inherited disorders that are affecting millions globally.

According Jennifer Doudna, a biologist at the University of California Berkeley, with CRISPR, DNA sequences are arranged to be translated into RNA that is used to lead the CRISPR system to matching strands of DNA. Cas9, a CRISPR-produced enzyme, attaches to the newly found DNA and snips it into separate pieces, acting as a pair of microscopic scissors, completely detaching the targeted, negative gene.

Current treatment options for most genetic disorders only provide symptomatic relief. However, Scientists believe that this could be what cures the most toxic diseases.
