El mecanismo de la replicación del ADN del ortopoxvirus en el citoplasma
Cell
|December 1, 1981
Resumen
El ADN recientemente sintetizado del virus de la viruela del conejo forma concatámeres cabeza a cabeza y cola a cola. Estas estructuras se procesan en genomas de longitud unitaria durante la replicación viral, creando potencialmente duplicaciones de genes.
Área de la Ciencia:
- Virología Virología.
- Biología Molecular Biología Molecular
- Genética La genética.
Sus antecedentes:
- La replicación del ADN del ortopoxvirus ocurre en los virosomas citoplasmáticos.
- Comprender la síntesis del ADN viral es crucial para las estrategias antivirales.
Objetivo del estudio:
- Para dilucidar la estructura del recién sintetizado ADN del virus de la viruela del conejo.
- Proponer un mecanismo para la formación del genoma y la variación genética potencial.
Principales métodos:
- Análisis de las estructuras de ADN dentro de las células infectadas.
- Caracterización de los concatámeres de ADN viral.
Principales resultados:
- El ADN recientemente sintetizado del virus de la viruela del conejo existe predominantemente como concatámeres.
- Estos concatámeres presentan arreglos alternos de cabeza a cabeza y cola a cola.
- Los genomas de longitud unitaria se extirpan de estos concatámeres durante la morfogénesis.
Conclusiones:
- El ADN de Concatameric sirve como sustrato para la generación del genoma de longitud unitaria.
- Un mecanismo propuesto sugiere que las deleciones internas pueden conducir a repeticiones terminales invertidas y duplicaciones de genes antes de la escisión.

Retrovirus Life Cycles
43.0K
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...

The Replisome
31.2K
DNA replication is carried out by a large complex of proteins that act in a coordinated matter to achieve high-fidelity DNA replication. Together this complex is known as the DNA replication machinery or the replisome.
The synthesis of the leading and lagging strands is a highly coordinated process. To explain this, the “Trombone model” was proposed by Bruce Alberts in 1980. The DNA loop formation starts when a primer is synthesized on the parent lagging strand. The loop grows with...

LTR Retrotransposons
18.1K
LTR retrotransposons are class I transposable elements with long terminal repeats flanking an internal coding region. These elements are less abundant in mammals compared to other class I transposable elements. About 8 percent of human genomic DNA comprises LTR retrotransposons. Some of the common examples of LTR retrotransposons are Ty elements in yeast and Copia elements in Drosophila.

Replication in Eukaryotes
15.4K
In eukaryotic cells, DNA replication is highly conserved and tightly regulated. Multiple linear chromosomes must be duplicated with high fidelity before cell division, so there are many proteins that fulfill specialized roles in the replication process. Replication occurs in three phases: initiation, elongation, and termination, and ends with two complete sets of chromosomes in the nucleus.

Viruses with RNA Genomes
1.5K
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...
