Methods for Gene Editing [1]

Gene editing, one of the key tools in synthetic biology, allows scientists to manipulate the DNA of organisms to create new functions, optimize metabolic pathways, and engineer new traits. In recent years, the development of new gene editing tools, such as CRISPR-Cas9, has made gene editing faster, cheaper, and more precise than ever before.

Methods for gene editing

CRISPR-Cas9

CRISPR-Cas9 is a revolutionary gene editing tool that uses a molecular complex composed of a guide RNA (gRNA) and a Cas9 protein. The gRNA guides the Cas9 protein to a specific location in the genome where it can make a double-stranded break. This break is then repaired by the cell's own DNA repair machinery, which can introduce desired genetic changes.

Multiplex Genome Editing by Natural Transformation (MuGENT)

MuGENT is a gene editing method that utilizes the natural transformation process in bacterial cells to introduce multiple edits into the genome simultaneously. This technique is particularly useful for making multiple changes in the bacterial genome without the need for complex molecular biology techniques.

Genome synthesis

Genome synthesis is the process of creating artificial DNA sequences in a laboratory. This technique is highly valuable for gene editing as it allows scientists to design and engineer synthetic genes or whole genomes for various purposes, including gene therapy, drug development, and studying genetic diseases.

Homologous Recombination (HR)

Homologous recombination is a natural DNA repair process that can be harnessed for gene editing. In this method, a piece of DNA containing the desired genetic changes is introduced into the cell, and the cell uses its homologous recombination machinery to incorporate this DNA into the genome, replacing the target sequence.
