Answers
For you, a CAS offers a completely paperless environment—relieving the administrative burdens of processing applications, while simultaneously increasing the accuracy of the data you're collecting. Consider the amount of time you spend today verifying prerequisites, calculating GPAs, and authenticating transcripts.
Q : What are the advantages of CRISPR-Cas9?
A : The CRISPR-Cas9 system is perhaps the most remarkable recent breakthrough in genome editing technology. CRISPR is a ubiquitous family of clustered repetitive DNA elements present in 90% of Archaea and 40% of sequenced Bacteria. CRISPR arrays consist of interspersed identical REPEAT sequences (21-48bp) and several unique invader-targeting SPACER sequences (26-72bp). The CRISPR-Cas9 genome editing system consists of two components: a “guide” RNA (gRNA) and a non-specific CRISPR-associated endonuclease (Cas9). The Cas9 protein is an endonuclease that uses gRNA to form base pairs with DNA target sequences, enabling Cas9 to introduce a site-specific double-stranded break in the DNA. Through RNA-directed Cas9 nucleases, the CRISPR-Cas9 system can modify DNA with greater precision than existing technologies like TALEN and ZFN.
