Which of the following is/are feasible within the context of phage research and phage therapy?

I. A cocktail of phages personally tailored to an individual’s infection could be used to combat a specific type of antibiotic-resistant bacteria.
II. A protein molecule used by the phage to kill the host bacteria could be developed into a potential therapeutic agent.
III. Given the extraordinary number of viruses on the planet and the power of DNA sequencing technology, it is likely we might find new genes and thus new proteins that could help in the fight antibiotic-resistant pathogens.
IV. Clinical trials using greater numbers of human subjects will shed more light on the potential therapeutic benefits of phage therapy.

To determine which of the statements are feasible within the context of phage research and phage therapy, we can analyze each statement individually:

I. A cocktail of phages personally tailored to an individual’s infection could be used to combat a specific type of antibiotic-resistant bacteria.

This statement is feasible within the context of phage research and therapy. Phage therapy involves using bacteriophages (viruses that infect bacteria) to kill specific bacteria. By creating a cocktail of phages specifically tailored to an individual's infection, it is possible to target and combat a specific type of antibiotic-resistant bacteria.

II. A protein molecule used by the phage to kill the host bacteria could be developed into a potential therapeutic agent.

This statement is also feasible within the context of phage research and therapy. Phages use various mechanisms to kill host bacteria, and some of these mechanisms can involve protein molecules. By studying and understanding these protein molecules, it is possible to develop them into potential therapeutic agents for treating bacterial infections.

III. Given the extraordinary number of viruses on the planet and the power of DNA sequencing technology, it is likely we might find new genes and thus new proteins that could help in the fight against antibiotic-resistant pathogens.

This statement is also feasible within the context of phage research and therapy. There are an immense number of viruses on the planet, many of which have not been fully characterized. With the power of DNA sequencing technology, it is possible to explore and identify new genes and proteins that could potentially aid in fighting antibiotic-resistant pathogens.

IV. Clinical trials using greater numbers of human subjects will shed more light on the potential therapeutic benefits of phage therapy.

This statement is feasible within the context of phage research and therapy. Clinical trials involving larger numbers of human subjects can provide valuable insights and data on the therapeutic benefits of phage therapy. These trials can help determine the safety, effectiveness, and potential side effects of using phage therapy as a treatment option.

In summary, based on the context of phage research and therapy, all the statements listed (I, II, III, and IV) are feasible.
