(there are multiple right answers to this homework question but I can't tell which one is right) You are designing a phage therapy for a cystic fibrosis patient with an multi-antibiotic resistant Mycobacterium infection. The Mycobacterium infection is preventing the patient from taking immunosuppressant drugs that are needed for a successful lung transplant. The idea is that introducing the right phage to the patient will kill the Mycobacterium cells and allow the patient to go on immunosuppressant drugs that will ensure the new lung is not rejected by the body. In the first step of your phage therapy design process, you isolate the exact Mycobacterium strain from the patient. What is the most important thing must you establish next about this bacterial isolate? That the isolate is genomically stable so you can study it That the isolate is similar to Mycobacterium in other patients That the isolate rapidly evolves due to horizontal gene transfer That the Mycobacterium is evading the immune system using a capsule

Viral Replication

The virus is acellular and considered non-living outside the host cell. The replication of the virus occurs only inside the living cells. Only a few genes are present in the smallest virus, whereas many genes are present in the largest virus. These genes encode specific viral proteins.
