Pls help me with the structure of a virus

The genetic material can be either DNA or RNA, and it can be single-stranded or double-stranded. This material contains the instructions for making new viruses.

The protein coat is called a capsid. It's made up of smaller protein units called capsomeres. The capsid protects the genetic material and helps the virus attach to and enter host cells.

Some viruses also have an outer envelope, which is a lipid bilayer derived from the host cell membrane. Viruses with envelopes are called enveloped viruses, while those without are non-enveloped or naked viruses. The envelope often contains viral proteins that help with attachment and entry into host cells.
