Poster Abstract
The CRISPR (clustered regularly interspaced short palindromic repeats)-Cas (CRISPR-associated proteins) system derived from Streptococcus pyogenes uses a Cas9 nuclease protein guided by two small RNA sequences, the tracrRNA and a targeting crRNA containing a 20 nucleotide guide sequence complementary to the genomic target of interest, to create double-strand DNA breaks (Figure 1). The double-strand DNA break is repaired by either non-homologous end joining (NHEJ) or homology-directed repair (HDR) by endogenous mechanisms within the mammalian cells. NHEJ often results in small insertions or deletions (indels) that produce functional gene knockouts through nonsense mutations or introduction of a stop codon. Report abuse »
