Question: give two other names used for the protein coat of a virus
Answer: These viral particles , also known as virions , consist of two or three parts : ( i ) the genetic material made from either DNA or RNA , long molecules that carry genetic information ; ( ii ) a protein coat , called the capsid , which surrounds and protects the genetic material ; and in some cases ( iii ) an envelope of lipids that surrounds the protein coat when they are outside a cell .
