Size and Structure of Viral Genomes01:26

Size and Structure of Viral Genomes

993
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...

Viral Structure00:56

Viral Structure

75.5K
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.

Protein Complex Assembly02:41

Protein Complex Assembly

17.0K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types.  Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
Many viruses self-assemble into a fully functional unit using the infected host cell to...

Introduction to Virus

2.3K
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...

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

50.3K
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...

Area of Science:

  • Ecology
  • Epidemiology
  • Virology

Background:

  • Arbovirus transmission involves complex interactions between viruses, vectors (e.g., mosquitoes), and vertebrate hosts.
  • These interactions are influenced by both biotic factors (viral strain, host susceptibility) and abiotic factors (climate, land use).
  • Climate change is predicted to alter landscape dynamics, impacting arbovirus transmission patterns.

Purpose of the Study:

  • To understand how the interconnectedness of mosquito biology, virus characteristics, and climate influences arbovirus transmission intensity.
  • To anticipate evolving patterns of arbovirus activity in a changing environment.

Main Methods:

  • The study synthesizes existing knowledge on the factors influencing arbovirus transmission.
  • It emphasizes the importance of vector competence, survivorship, and feeding behavior in assessing risk.

Main Results:

  • Climate change, as per IPCC reports, will likely lead to landscape alterations affecting arbovirus transmission.
  • Understanding the interplay of viral, vector, and host factors is key to predicting transmission dynamics.

Conclusions:

  • Predicting arbovirus activity in a changing climate requires a comprehensive understanding of vector-virus-host-environment interactions.
  • Assessing vectorial capacity is essential for risk estimation and developing effective control strategies.
