In bacteria and archaea, CRISPR–Cas(clustered regularly interspaced short palindromic repeats and CRISPR-associated genes) systems provide RNA-guided [ribonucleic acid-guided] adaptive immunity againstinvaders such as viruses and plasmids... CRISPR–Cas systems are diverse... In all... CRISPR–Cas systems, adaptive immunity consists of three stages : adaptation to novel invaders, CRISPRRNA(crRNA) biogenesis, and invader silencing. During adaptation, short fragments of DNA called "protospacers" are recognized and excised from invader DNA and then processed and integrated into CRISPR arrays(where the same sequences are called "spacers") for use in future invader silencing. 2, record 1, English, - protospacer

The rearrangement of genes from two distinct influenza strains to produce a novel viral strain. 4, record 2, English, - reassortment
Record number: 2, Textual support number: 1 CONT
One of the ways that a pandemic strain can arise. A strain from nature that can’t easily infect humans encounters a strain that can, generally in a pig. The two viruses swap genetic material, giving the novel strain the ability to jump easily into humans. 5, record 2, English, - reassortment
Record number: 2, Textual support number: 1 OBS
As populations will have no immunity to the new subtype, and as no existing vaccines can confer protection, antigenic shift has historically resulted in highly lethal pandemics. For this to happen, the novel subtype needs to have genes from human influenza viruses that make it readily transmissible from person to person for a sustainable period. 6, record 2, English, - reassortment

Réassortiment. De nouvelles souches de grippe peuvent apparaître quand deux virus différents infectent la même cellule. Des copies de leurs ARN [acide ribonucléique] peuvent se mélanger et produire une descendance dotée de combinaisons de gènes provenant de chacun des deux virus parents. De cette façon, une souche de grippe d'oiseau ou d'un autre animal peut acquérir des gènes lui conférant la capacité de se propager plus facilement chez l'homme. 5, record 2, French, - r%C3%A9assortiment

Esto ocurre en infecciones mixtas de una sola célula con variantes de virus de genomas segmentados. Los viriones de la progenie pueden contener algunos segmentos de un progenitor, y algunos del otro. Este es un proceso eficiente observado en orthomyxovirus, reovirus, arenavirus, y bunyavirus.

Otra de las posibilidades, más probable, es que se produzca un reagrupamiento viral (fenómeno producido por el intercambio de material genético entre virus humanos y de aves durante la coinfección de un humano), lo que sería altamente peligroso. 6, record 2, Spanish, - rearreglo

Immunité antivirale.
