Viruses are classified into four groups based on shape: filamentous, isometric (or icosahedral), enveloped, and head and tail. Many viruses attach to their host cells to facilitate penetration of the cell membrane, allowing their replication inside the cell.

What are the characteristics for classification of viruses?
Four characteristics were to be used for the classification of all viruses: Nature of the nucleic acid in the virion. Symmetry of the protein shell. Presence or absence of a lipid membrane.
What are the three main types of viruses?
The Three Major Types of Computer Viruses
- Macro viruses – These are the largest of the three virus types. They use built-in programming scripts in such applications as Microsoft Excel and Microsoft Word to automate the tasks. ...
- Boot record infectors – These viruses are known also as boot viruses or system viruses. ...
- File infectors – These viruses target .
What are the 4 shapes of viruses?
Viruses come in many shapes and sizes, but these are consistent and distinct for each viral family. In general, the shapes of viruses are classified into four groups: filamentous, isometric (or icosahedral), enveloped, and head and tail.
What are the 6 classes of animal viruses?
The Baltimore Classification System
- Class I: Double stranded DNA (dsDNA) viruses. ...
- Class II: Single stranded DNA (ssDNA) viruses. ...
- Class III: Double stranded RNA (dsRNA) viruses. ...
- Class IV: Single stranded RNA (ssRNA) viruses. ...
- Class V: Single stranded RNA (ssRNA) viruses. ...
- Class VI: Positive-sense ssRNA reverse transcriptase viruses.
Why is classification of virus difficult?
Viruses are notoriously difficult to classify due to their enormous diversity, high rates of change and tendency to exchange genetic material.
How do virologists classify viruses?
A major branch of virology is virus classification. Viruses can be classified according to the host cell they infect: animal viruses, plant viruses, fungal viruses, and bacteriophages (viruses infecting bacteria, which include the most complex viruses).
