Resumen

La metagenómica ha ampliado enormemente nuestro conocimiento de la diversidad viral, particularmente los virus de ARN. Sin embargo, gran parte de la "materia oscura" en los genomas virales divergentes sigue sin caracterizarse.

Área de la Ciencia:

Virología
La genómica
La bioinformática

Sus antecedentes:

Los virus representan un vasto y poco estudiado dominio de la vida.
La metagenómica ha revolucionado la exploración de la diversidad microbiana y viral.
La virósfera conocida se ha expandido significativamente debido a los avances recientes.

Objetivo del estudio:

Discutir el impacto de la metagenómica en la comprensión de la diversidad de los virus de ARN.
Para resaltar los desafíos en curso en la caracterización del genoma viral.
Para abordar la "materia oscura" del material genético viral inexplorado.

Principales métodos:

Secuenciación y análisis metagenómicos.
Enfoques bioinformáticos para la reconstrucción del genoma viral.
Genómica comparativa para la evaluación de la diversidad viral.

Principales resultados:

La metagenómica ha revelado una diversidad sin precedentes dentro de los virus de ARN.
Porciones significativas de los genomas virales permanecen sin caracterizar ("materia oscura").
Se han identificado nuevos linajes virales y familias de genes.

Conclusiones:

La metagenómica es crucial para expandir la virósfera conocida.
Se necesita más investigación para caracterizar los genomas virales divergentes.
La comprensión de la 'materia oscura' viral es clave para comprender la evolución y la ecología viral.

Quantifying Work

Quantifying Work

As a system undergoes a change, its internal energy can change, and energy can be transferred from the system to the surroundings, or from the surroundings to the system.

Seed Structure and Early Development of the Sporophyte

Seed Structure and Early Development of the Sporophyte

Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo.

Exceptions to the Octet Rule

Exceptions to the Octet Rule

Many covalent molecules have central atoms that do not have eight electrons in their Lewis structures. These molecules fall into three categories:

Calculating Equilibrium Concentrations

Calculating Equilibrium Concentrations

Being able to calculate equilibrium concentrations is essential to many areas of science and technology—for example, in the formulation and dosing of pharmaceutical products. After a drug is ingested or injected, it is typically involved in several chemical equilibria that affect its ultimate concentration in the body system of interest. Knowledge of the quantitative aspects of these equilibria is required to compute a dosage amount that will solicit the desired therapeutic effect.

Molecular Comparison of Gases, Liquids, and Solids

Molecular Comparison of Gases, Liquids, and Solids

Particles in a solid are tightly packed together (fixed shape) and often arranged in a regular pattern; in a liquid, they are close together with no regular arrangement (no fixed shape); in a gas, they are far apart with no regular arrangement (no fixed shape). Particles in a solid vibrate about fixed positions (cannot flow) and do not generally move in relation to one another; in a liquid, they move past each other (can flow) but remain in essentially constant contact; in a gas, they move...
