What is one function of the capsid found in viruses?

The function of the capsid in viruses is to protect the viral genetic material. The capsid is composed of protein subunits known as capsomers and surrounds the viral genome, which can be made up of RNA or DNA. This protective layer is crucial for the virus's integrity and stability, as it shields the genetic material from environmental factors such as enzymes, heat, and pH changes, which could potentially damage or degrade the genetic material. Additionally, the capsid plays a role in the delivery of the viral genome into host cells during the infection process.

The other options do not accurately represent the role of the capsid in viruses. It does not assist in metabolism, store energy, or form cellular structures, as these functions are associated with living cells and organisms rather than viruses, which are non-cellular entities reliant on host cells for reproduction and metabolic processes.
