Genome editing technology Genome editing technology enables genetic engineering where DNA is replaced, deleted or inserted in the genome of a living organism, and the emergence of CRISPR-Cas9 system has further facilitated the realization of precise genetic modifications. Gene mapping and precise genetic modifications by inducing targeted DNA double-strand breaks opened up new avenues for […]

The Multiple Application of CRISPR-Cas9
CRISPR-Cas9 gene editing technology can target virtually any genomic location of choice by utilizing a short RNA guide, then cut the sequence with the Cas9 protein. Compared with traditional gene editing technologies, the CRISPR-Cas9 system is both faster and more efficient. The CRISPR-Cas9 system currently has a wide variety of applications in gene engineering and […]
The History of CRISPR-Cas9
The CRISPR (Clustered regularly interspaced short palindromic repeats) system was first identified in archaea as an adaptive defensive mechanism that confers resistance to foreign genetic elements. Later on, the CRISPR-Cas system was engineered into a versatile gene-editing tool enabling manipulation of protospacer adjacent motif (PAM) downstream DNA. Now, CRISPR-Cas9 has facilitated robust genome editing in […]
What Are the Advantages of CRISPR-Cas9?
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 […]
