Subviral Agents01:29

Subviral Agents

273
Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

Viruses with RNA Genomes01:29

Viruses with RNA Genomes

333
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Viral Structure00:56

Viral Structure

69.6K
Viruses are extraordinarily diverse in shape and size, but they all have several structural features in common. All viruses have a core that contains a DNA- or RNA-based genome. The core is surrounded by a protective coat of proteins called the capsid. The capsid is composed of subunits called capsomeres. The capsid and genome-containing core are together known as the nucleocapsid.

Size and Structure of Viral Genomes

349
Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...

Retroviruses02:33

Retroviruses

13.3K
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’...

Introduction to Virus01:28

Introduction to Virus

628
Viruses are unique biological entities that blur the boundary between living and non-living systems. Although they lack cellular structure and metabolic processes, they can exhibit characteristics of life when infecting a host. Their defining feature is a nucleic acid core, composed of either DNA or RNA, encapsulated within a protein coat called a capsid. This simple structure allows them to invade host cells and use their machinery for replication efficiently.Viral Structure and...

  • Molecular Biology
  • Genetics

Background:

  • RNA viruses require mechanisms to protect their genetic material within host cells.
  • Polysomes, strings of ribosomes on mRNA, are essential for protein synthesis.

  • To describe two potential types of polysomally protected viruses.

Main Methods:

  • Theoretical modeling of viral RNA-ribosome interactions.
  • Analysis of viral genome properties, including reading frames and stop codons.
  • Comparison of theoretical predictions with existing ribosome profiling data.

Main Results:

  • Two types of polysomally protected viruses (type 1 and type 2) are proposed.
  • Type 2 viruses are predicted to possess ambigrammatic RNA sequences, lacking stop codons in a reverse reading frame.
  • Observed ribosome profiles of narnaviruses align with predictions for type 2 viruses.

Conclusions:

  • Polysomal protection is a conceivable strategy for RNA viruses.
  • Ambigrammatic RNA sequences are a key characteristic of type 2 polysomally protected viruses.
  • Ribosome profiling offers a viable method for identifying these viruses.
