CRISPR-Cas9, short for clustered regularly interspaced short palindromic repeats, is a molecular biology tool used to selectively modify the DNA of living organisms. It came to be when ------- discovered the mechanism by which a bacterial protein called Cas9 cleaves DNA. Which choice completes the text so that it conforms to the conventions of Standard English?biochemists, Emmanuelle Charpentier and Jennifer Doudnaeliminatebiochemists Emmanuelle Charpentier and Jennifer Doudna,eliminatebiochemists Emmanuelle Charpentier and Jennifer Doudnaeliminatebiochemists, Emmanuelle Charpentier and Jennifer Doudna

29. Which of the following about CRISPR-Cas9 technique is correct?1. Catalytically inactive Cas-9 (dCas9) cuts only one strand of DNA as opposed to both.2. The guide RNA used in the lab is analogous to the tracrRNA/crRNA hybrid in the adaptive immunesystem of bacteria.3. Homology directed repair can only allow for editing a single base pair.4. NHEJ can lead to mutations.A. 1, 2 and 3B. 1 and 3C. 2 and 4D. 4 onlyE. All of 1, 2, 3 and 4 are correc

What is the main function of the CRISPR-Cas9 system?

Which of the following definitions correctly describes the CRISPR-Cas9 system?ANSWERAn expression system that is engineered to make large quantities of a desired proteinThe process of using viruses to introduce genetic material into human cells to treat diseaseSensitive rapid diagnostic tests that detect antigens or antibodies in a sampleA gene-editing tool that locates a specific DNA sequence and cuts it out so that a new sequence can be inserted

The development of CRISPR-Cas9, a powerful gene-editing tool, has sparked debate. How do the viewpoints of science and religion MOST LIKELY differ regarding this technology?Read Less(a) Science prioritises the potential cures for diseases offered by CRISPR, while religion focuses on the risks of unintended consequences.Read Less(b) Science emphasises the need for strict regulations to govern CRISPR use, while religion promotes widespread adoption for human enhancement.Read Less(c) Science believes CRISPR can bring people back to life, while religion views it as an extension of medical treatments. (d) Science focuses on the technical feasibility of CRISPR, while religion emphasises the ethical implications of altering human genes.

1. The discovery has opened new avenues for research and potential treatments for various diseases.2. The ethical implications and potential risks of such technologies, notwithstanding their benefits, need careful consideration.3. Advances in genetic engineering, such as CRISPR-Cas9, have enabled precise manipulation of DNA sequences.4. Scientists can now potentially correct genetic mutations, prevent hereditary conditions, and even engineer more resilient crops.
