Retrovirus Life Cycles01:10

Retrovirus Life Cycles

45.8K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Retroviruses

12.2K
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

Non-LTR Retrotransposons03:18

Non-LTR Retrotransposons

11.5K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

Viral Recombination00:57

Viral Recombination

23.4K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Viral Mutations00:36

Viral Mutations

32.2K
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Area of Science:

  • Virology
  • Archaea biology
  • Molecular biology

Background:

  • The Turriviridae family comprises dsDNA viruses infecting extremophilic archaea.
  • Virions are spherical, approximately 75 nm in diameter, with a lipid membrane and protein capsid.

Purpose of the Study:

  • To summarize the International Committee on Taxonomy of Viruses (ICTV) report on the family Turriviridae.
  • To provide an overview of the taxonomy, structure, and host interactions of Turriviridae viruses.

Main Methods:

  • Review and synthesis of data presented in the ICTV report.
  • Analysis of viral genome, virion structure, and host-archaea interactions.

Main Results:

  • Turriviridae viruses possess dsDNA genomes (16-17 kbp) and infect archaea in the genera Sulfolobus and Saccharolobus.
  • Infection by Sulfolobus turreted icosahedral virus 1 leads to cell lysis, while other family members can be temperate.

Conclusions:

  • The ICTV report provides a comprehensive taxonomic overview of the Turriviridae family.
  • Understanding Turriviridae is crucial for archaeal virology and extremophile research.
