Detailed explanation-1: -A: CRISPR genome editing allows scientists to quickly create cell and animal models, which researchers can use to accelerate research into diseases such as cancer and mental illness. In addition, CRISPR is now being developed as a rapid diagnostic.
Detailed explanation-2: -CRISPR/Cas9 edits genes by precisely cutting DNA and then letting natural DNA repair processes to take over. The system consists of two parts: the Cas9 enzyme and a guide RNA. Rapidly translating a revolutionary technology into transformative therapies.
Detailed explanation-3: -CRISPR/Cas9 works by cutting a DNA sequence at a specific genetic location and deleting or inserting DNA sequences, which can change a single base pair of DNA, large pieces of chromosomes, or regulation of gene expression levels.
Detailed explanation-4: -Attacking the cancer. Some scientists have used CRISPR to supercharge the immune system’s T cells. Turning off cancer’s defenses. T cells aren’t supposed to attack normal cells. Slowing down cancer. Another lab used CRISPR to change genes in cancer cells. 27-Jan-2022
