Main Body

CRISPR technology is an advanced gene editing tool which acts as a molecular scissor to cleave harmful gene (e.g. arranged) and replace them with target genes. It addresses the genetic cause of disease. CRISPR is also used to introduce desirable trait in organisms such as higher yield in plants & self-termination in mosquitoes. Recent developments1) CRISPR-CAS9 is used to treat forms of cancer such as blood cancer, home armed eh. 2) Used to correct gene defects pertaining to dysfunction of various body part. e.g. Sickle cell anaemia.
3Used in biotechnology to improve food nutrition, crop yield and disease resilience. 4) Used to enhance yield of crops like Jatropha for biofuel production. Opportunities: 1) Curing cancer and other genetic diseases. 2) Preventing disease by making alterations to gametes. 3) Food and nutritional security. 4) Energy security through biofuels. 5) Modifying body immunity to better fight infections. Ethical challenges: 1) Risk of genetic divide - accessibility to treatment only to the wealthy. 2) Designed babies and 'perfected' genomes → unintended health effects. 3) GMM crops → bio-contamination, unintended health effects. 4) Issues of safe affect such as gene rejection, cytokine storm, auto-immune dysplance etc.
