What are the 7 classifications of viruses?
What are the 7 classifications of viruses?
The seven classes of viruses in the Baltimore Classification System are as follows:
- 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.
What are the four classification of viruses?
On the basis of shared properties viruses are grouped at different hierarchical levels of order, family, subfamily, genus and species.
What are the main classifications of viruses?
Baltimore Classification
- Group I viruses contain double-stranded DNA (dsDNA) as their genome.
- Group II viruses have single-stranded DNA (ssDNA) as their genome.
- Group III viruses use dsRNA as their genome.
- Group IV viruses have ssRNA as their genome with a positive polarity.
What are the 3 ways of classifying viruses?
Based on their host, viruses can be classified into three types, namely, animal viruses, plant viruses, and bacteriophages.
What are the 6 classes of viruses?
Classification
- Group I: double-stranded DNA viruses.
- Group II: single-stranded DNA viruses.
- Group III: double-stranded RNA viruses.
- Group IV: positive sense single-stranded RNA viruses.
- Group V: negative sense single-stranded RNA viruses.
- Group VI: single-stranded RNA viruses with a DNA intermediate.
How are viruses classified into families?
1 Viral families are designated with the suffix viridae. Families are distinguished largely on the basis of physiochemical properties, genome structure, morphology, and gene expression.
How are viruses classified and named?
The highest taxonomic group among viruses is the family; families are named with a suffix -viridae. Subfamilies have the suffix -virinae; genera the suffix -virus. The prefix may be another latin word or a sigla, i.e., an abbreviation derived from some initial letters.
What are 5 characteristics of viruses?
These are: 1) attachment; 2) penetration; 3) uncoating; 4) replication; 5) assembly; 6)release. As shown in , the virus must first attach itself to the host cell. This is usually accomplished through special glycoprotiens on the exterior of the capsid, envelope or tail.
What are 4 characteristics of viruses?
Characteristics
- Non living structures.
- Non-cellular.
- Contain a protein coat called the capsid.
- Have a nucleic acid core containing DNA or RNA (one or the other – not both)
- Capable of reproducing only when inside a HOST cell.

What are the two basic components of viruses?
Viruses are very small infectious particles consisting of nucleic acid enclosed in a protein coat and, in some cases, a membranous envelope.
How are viruses classified and why?
Virus classification is based mainly on characteristics of the viral particles, including the capsid shape, the type of nucleic acid (DNA or RNA, double stranded (ds) or single stranded (ss)) within the capsid, the process of replication, their host organisms, or the type of disease they cause.
What are the 3 types of viruses Class 11?
Animal viruses:- Those viruses which infect animals and causes various diseases. For example, Retrovirus.

What are viruses and its types?
Multipartite Virus – A virus which can attack both, the boot sector and the executable files of an already infected computer is called a multipartite virus. If a multipartite virus attacks your system, you are at risk of cyber threat….Types of Computer Virus.

What is virus write its types?
A virus is a fragment of code embedded in a legitimate program. Viruses are self-replicating and are designed to infect other programs. They can wreak havoc in a system by modifying or destroying files causing system crashes and program malfunctions.
