Question

Explain the structure and types of virus?​

Answer 1

Answer:

The simplest virus consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virus to specific receptors exposed on the prospective host cell.

$\huge\blue{Answer}$

Structure of Virus

All viruses contain nucleic acid, either DNA or RNA (but not both), and a protein coat, which encases the nucleic acid. Some viruses are also enclosed by an envelope of fat and protein molecules. In its infective form, outside the cell, a virus particle is called a virion.

Types of virus

Viruses are classified into four groups based on shape

1. filamentous
2. isometric (or icosahedral)
3. enveloped
4. head and tail
