CRISPR-Cas9 Synthesis

CRISPR-Cas9 is a method of gene editing that provides researchers with a way of precisely targeting a specific string of DNA. CRISPR is a sequence of repeated DNA located in the genomes of bacteria that are used in immune systems to help protect our bodies from infecting viruses. This method involves the use of an enzyme known as Cas9 and a guide RNA. A virus’s DNA becomes spacers in the CRISPR sequence when the new virus infects the bacterium. This sequence will then begin the process of transcription in which it will become a guide RNA. This RNA will then be used to guide the Cas9 to locate the target sequence within the viral genome, so that the Cas9 can snip off this sequence and kill the virus. Simply put, it’s like using scissors
