Question

1. what types of cells can viruses be specifically designed to target? select all that apply.

brain cells
bacteria cells
cancer cells
genetic cells

Explanation:

• Brain cells: Viruses can be engineered (e.g., in gene therapy or research) to target brain cells for treating neurological conditions or studying brain biology.
• Bacteria cells: Bacteriophages are viruses that specifically target bacteria cells, and synthetic viruses can also be designed for this purpose (e.g., to combat antibiotic - resistant bacteria).
• Cancer cells: Oncolytic viruses are designed to specifically target and destroy cancer cells, using the cancer cells' biology to replicate and kill them while sparing normal cells.
• Genetic cells (assuming this refers to cells with specific genetic targets or stem cells/genetically modified cells): Viruses can be designed to target cells based on genetic markers, for example, in gene therapy to deliver genetic material to cells with specific genetic profiles.

Answer:

brain cells, bacteria cells, cancer cells, genetic cells
