Question

Viruses have two main structures: a(n) _____ and genetic material.

Answer 1

These viral particles, also known as virions, consist of two or three parts: the genetic material made from either DNA or RNA, long molecules that carry genetic information, a protein coat, called the capsid, which surrounds and protects the genetic material.

Answer 2

Answer: C. capsid

Explanation:

All viruses have the same basic structure: a core of nucleic acid surrounded by protein. Individual viruses contain only a single type of nucleic acid, either DNA or RNA. Viruses are frequently classified by the nature of their genomes. RNA-based viruses are known as retroviruses. Nearly all viruses form a protein sheath, or capsid, around their nucleic acid core. The capsid is formed of one to a few different protein molecules duplicated many times. In some viruses, specific enzymes are stored within the capsid.
