What describes the similar functions of capsids and nuclear membranes

Answer 1

The nuclear membrane is a semi-permeable, flexible membrane surrounding the nucleus of a cell. A capsid is the protein "jacket" that forms the body of a virus. The main job of the nuclear membrane is to contain and protect the genetic code of the cell: its DNA. Likewise, the main job of a capsid is to contain and protect the genetic code of the virus: its RNA.
