I’m having trouble finding the answer to the problem can you please help? Like many biotechnologies, CRISPR/Cas9 was originally discovered as system that naturally occurs in species and was later modified for researchpurposes. What is CRISPR/Cas9's role in "naturally occurring" conditions?CRISPR/Cas9 is used in some bacteria as an immune system to fight infection by viruses.CRISPR/Cas9 is used in special bacteria to perform DNA replication at high temperatures.CRISPR/Cas9 is used during translation to ensure tRNA and rRNA make correct 3D-shapes.CRISPR/Cas9 is one of the restriction endonucleases that cut at palindromic sites in the genome.CRISPR/Cas9 is used during DNA repair to conduct proofreading and identify template strands.

Biotechnology is the branch of biology which deals with the utilisation of cells and biomolecular process for the formation of various products which are needed in different areas like treatment and research Types of biotechnology -- medical biotechnology industrial biotechnology environmental biotechnology marine biotechnology Uses of biotechnology -- It has been used to develop various products which are rich in contents and are beneficial for human health like modified rice having high vitamin A content It is also useful in preventing diseases Bacteria have evolved various mechanism to resist against the viruses like bacteriophage some of these defence mechanism are -- Change in envelope of bacteria Restriction modification systems Adaptive immunity via CRISPR CAS9 system CRISPR CAS9 system is special defence mechanism in bacteria which help it from the attack of virus like bacteriophage Mechanism of CRISPR CAS9 -- When the virus { bacteriophage } infects the bacteria the bacteria the some part of viral DNA gets incorporated into the CRISPR CAS9 region of bacterial genome and when the bacteria again gets infected with virus this system recognise the virus and activate enzymes to cleave that portion of genome rendering the virus harmless So correct answer is option 1 i.e it protects the bacteria from the virus infection
