Main Article Content

Objective: The applicability in reverse genetics studies, animal model experiments and also in curing diseases caused by viruses like HIV makes the CRISPR-Cas9 system a highly desirable technique with the ability to achieve quick plausible outcomes. The bacterial cells chop up the viral genome. And its search of these pieces of spacer DNA. The spacer DNA is nothing but pieces of the different viral genome. That had infected the cell previously. So each time of bacteriophage infects the cell take it pieces and search of spacer DNA. The interference is between the specific Cas protein and RNA Sequence has going to be merged together. The Crispr system would be somehow like adopted immune system in human. it would kind of memory to prevent this same bacteriophage for infecting the cell other time.

Purpose (Hypothesis): This article main purpose to describe the Genome editing enabled by the development of tools to make precise, targeted changes to the genome of living cells.

Methods (Technique): CRISPR-Cas9.

Conclusion: The CRISPR-Cas9 is the key to genetic revaluation era. This tool is very useful for studying the genetic code. at finally in this review both in modelling and the CRISPR/Cas9 system have emerged as a feasible tool to achieve what has seemed impossible for decades.

Genetic code, bacterial genome, viruses, DNA, RNA.
