Answer:
Answer is E. sets of identical proteins.
Step-by-step explanation:
A virus is an example of microorganisms and it is considered to be the deadliest. It made up of capsid, which is the protein shell, that protects the RNA or DNA, which is its nucleic acid genome.
Microtubules are the microscopic structure, which are tubular in nature, found in the cytoplasm. They support and give shape to the cell.
The actin filaments serve as track for the movement of myosin , which is the motor protein. It also help in the formation of long filaments by joining many molecules together.
The spherical shell is the shape of the virus.
They are all built by proteins which are identical.
