Frequently Asked Questions

What type of viruses contain RNA instead of DNA?

The first human virus discovered was the yellow fever virus in 1901 by Walter Reed. A virus that contains RNA instead of DNA is sometimes called a retrovirus. There are two main types of reproductive cycles for viruses: the lytic cycle and the lysogenic cycle.

What is the difference between DNA viruses and RNA viruses?

Differences Between DNA and RNA Viruses. Viruses are infectious biological agents that are completely dependent on the host cell in order to complete their replication process, transcription of the genome, and translation of the mRNA transcripts into proteins. Unlike most living things, the viruses do not have cells.

Are there any viruses that contain both RNA and DNA?

There are DNA viruses, and then there are RNA viruses. However, there are no viruses I know of that are both RNA and DNA. DNA viruses still require cell mechanisms of transcription into RNA, though, and some RNA retroviruses convert their RNA into DNA upon entering a cell.

What are 3 major differences between DNA and RNA?

This arrangement of DNA strands is called antiparallel. The asymmetric ends of DNA strands are referred to as the5′ (five prime) and3′ (three prime) ends. One of the major differences between DNA and RNA is the sugar, with2-deoxyribose being replaced by the alternative pentose sugar ribose in RNA.
