WebCRISPR Cutout was designed for non-scientists and science students. This app is awesome for use in the biomedical science curriculum in high school or in higher education. CRISPR Cutout focuses on meeting the following learning objectives: 1. Identify the nucleotides that makeup RNA and DNA. 2. Match correct nucleotides between RNA and DNA. 3. WebThe CRISPR role/method is used in bacterial cells to protect themselves from infection by viruses. When the cells detect presence of viruses, it produces two types of RNA (short) where one sequence matches the sequence of the invading virus. The two RNAs join with a protein to. form a complex known as Cas-9; a nuclease enzyme that can cut DNA.
