The recent breakthroughs in biotechnology haveintroduced novel approaches in DNA and RNA manipulation and this has laid thefoundation for genome engineering and its subsequent applications. The researchand applications of genetic engineering are changing our lives every day withthe possibilities of life extension and improved health. The potential for creatingdisease-resistant viruses is opening up new ways to fight against every commondisease. In the years to come, the applications of genetic engineering willundoubtedly lay the foundation for new technologies and medical breakthroughs.
The CRISPR (clustered regularly interspersed shortpalindromic Repeat) -cas9 gene-editing system has recently transformed thefield of genomeengineering by revolutionizing thescience of genetic modification. It is an extremely fast, highly specific, andversatile technique for precise genetic modification of living cells using anRNA guide. The Cas9 protein is made up of three amino acids which can beinserted into nucleases or strands of living matter in an organism's nucleus.Once inserted, the Cas9 RNA guides the genetic scissors that cut through thedouble-stranded DNA that is part of the DNA helix.
