During the past few years gene researchers worldwide have elaborated a new technology which contributes to making certain modifications in the DNA. In comparison to prior methods of DNA alteration, the recent approach is much easier, faster and cheaper. Moreover it has more accuracy. The new technology is called CRISPR and has already changed the way of arranging basic research. The geneticists and medical researchers have got the new way of thinking about treating diseases.
CRISPR regards a distinctive organisation of DNA sequences, which are contained in the genomes of microorganisms. These sequences seem harmless, however, they form a core element of their immune systems, which is responsible for protection of an organism’s well-being and health. Bacterial cells, just like human ones, can be intruded by viruses that are infective agents. In this case the CRISPR system can repel the offensive: it destroys the genome of the intruding virus. That genome contains genetic material, which is needed to replicate the virus. In that way the CRISPR immune system defends microorganisms from spread of the virus. Continue reading
