The state where a cell contains polytene chromosomes.  2, fiche 3, Anglais, - polyteny

Record number: 3, Textual support number: 1 CONT

The polyteny phenomenon [in Drosophila melanogaster polytene chromosomes] involves at least two events. First, the centromeres belonging to all of the four pairs of fruit fly chromosomes fuse in a heterochromatic structure named chromocenter. Almost simultaneously, a somatic pairing of homologues takes place, followed by a polytenisation phenomenon(i. e. many rounds of replication of the euchromatin without subsequent separation of chromatids).  3, fiche 3, Anglais, - polyteny

Le phénomène de polyténie a été principalement décrit dans les cellules des glandes salivaires de la larve de drosophile. À l'interphase mitotique, les chromosomes homologues restent appariés, et leur ADN se réplique sans division cellulaire ni même nucléaire. Les répliques ne se séparent pas et les centromères fusionnent formant ainsi des chromosomes «géants» dont la structure chromatinienne est aisément observable en microscopie.  2, fiche 3, Français, - polyt%C3%A9nie

The Insect Habitat(IH) was designed to support a variety of insect species. However, during the initial flight increments, it will be dedicated to experiments using Drosophila melanogaster, or fruit flies. The Insect Habitat will enable studies of the fruit fly to learn how microgravity affects development, nervous system function, movement and behavior, growth, reproduction, aging, gene expression, mutagenesis from radiation and circadian rhythms or sleep/wake cycles.  2, fiche 4, Anglais, - insect%20habitat

The IH will support single- and multi-generation experiments that have approximate external dimensions of 13.5 cm (L) x 2.25 cm (D) x 7.0 cm (H) each. The flies will live in two chevron-shaped container elements. These containers can be divided into two parts using the internal food cylinders; this yields two 55 ml containers that can support up to 100 Drosophila through to egg-laying. Alternatively, the containers can be left undivided, which yields a single 110 ml volume that supports up to 200 Drosophila. ... The two insect containers reside in the science element portion of the IH. The science element consists of two environmentally controlled "drawers." Each drawer contains a centrifuge that can provide up to 2G. Each centrifuge will hold six insect containers. Typically, one drawer will have a microgravity environment and the other drawer will have a defined gravity environment, although the precise gravity regimen for each centrifuge can be determined by the researcher.  2, fiche 4, Anglais, - insect%20habitat

Habitats in the Space Station Fundamental Biology Research Facility (SSFBRF) enable studies on a variety of organisms across multiple science disciplines. They allow scientists to conduct experiments in habitats that are similar in design to those that have been used in labs for ground studies. Each habitat provides life support, environmental control, and monitoring systems and can be housed in one or more of the three major host systems: the Centrifuge, Life Sciences Glovebox, and Habitat Holding Rack. This hardware was designed to automate as much as possible, thus providing maximizing science return while requiring minimal crew time.  5, fiche 4, Anglais, - insect%20habitat
