It offers hope to patients; since there is a lot of fatality rate among the newborns in the United States resulting from the disorder, by using the technology, their hopes can be restored. We think we know what were doing, and we think were measuring exactly what changes were doing to the genes, but theres always the possibility that either we miss something or our technology cant pick up on other changes that have been made that havent been directed by us. Its changing pretty fast. In order to reduce the mistakes that can occur without enough practice, there is a modified version of Cas9 that is available that will help to create just a nick in one strand and not two together so that you can amend the changes a little and are known as Cas9 nickase. The researcher has to see then that he can bring out the results with an optimized approach during the editing process. PS4 Pros and Cons Is It Worth The Money? This was very well executed when there was a necessity for the cancer cell lines to be chopped out of 18,000 genes. We take a look at the history of genomic sequencing, where it's going in the future, and the power it has to potentially treat diseases like cancer. If you happen to go off target, you can create mutations that are unwarranted modifications. Mutations can be introduced in multiple genes at the same time by injecting them with multiple gRNAs. While the benefits of CRISPR range from curing genetic conditions to organ transplants, ethicists fear its use in promoting desired traits rather than life-saving traits such as intelligence that could have long-term implications.
