DNA repair technology
A technology named clustered regularly interspaced short palindromic repeat shortened to CRISPR-Cas9 was discovered in 2012. The new technology allows anyone with molecular biology training to alter the genes of any species with precision. It is a cheaper, more efficient and precise than other technologies. With the help of CRISPR–Cas9,parts of a genome can be edited by scientists by removing or adding or altering parts in a DNA sequence. It has a range of potential applications in treating medical conditions like cancer and hepatitis B. Other genome editing tools include zinc–finger nucleases (ZFNs) and transcription activator-like effector nucleases (TALENs) where double-stranded breaks are introduced to activate repair pathways. However, these methods consume a lot of time and are even costly.
