If mutation destroys the function of the Cas9 gene then the bacteria will not be able to target a specific bacteriophage for destruction upon infection for the second time.
<h3>What is the Cas9 gene?</h3>
- Cas9 is a 160 kilodalton protein that plays a vital role in the immunological defense of certain bacteria against DNA viruses and plasmids and is heavily utilized in genetic engineering applications.
- Its main function is to cut DNA and thereby alter a cell's genome.
- Although Cas9 is an endonuclease and is evolved as a mechanism of immunity against viruses, they are not considered restriction enzymes.

Answer:
Ecosystems are influenced by both biotic and abiotic factors. Biotic factors include animals, plants, fungi, bacteria, and protists. Some examples of abiotic factors are water, soil, air, sunlight, temperature, and minerals.
Paul Zamecnik and his colleagues carried
out an experiment to track the fate of radioactive leucine molecules attached
to tRNAs (Transport RNAs). In their experiment, they found out that amino acids
are transferred from tRNAs to proteins. Paul Zamecnik, an American scientist, played
a major role in the early history of molecular biology.
