Which of the following best describes the purpose of the capsid?

• A protein structure that surrounds and protects the viral genome.

• A genome composed of Nucleic acid which codes for the viral structures.

• A protein structure which allows the virus to gain entry into a host cell.

• 1. An envelope of phospholipid which allows some viruses to merge with the host cell membrane.

• Oxygen

• Carbon Dioxide

• Water Vapor
