      Når transposonerne hopper ud og ind af generne kan de efterlade dele af deres DNA-sekvens eller tage et stykke af DNA-strengen med sig. Dette giver variation og dermed kan der ske evolution.

Transposonernes centrale dele centromerene er afgørende for at kromosomerne bliver fordelt korrekt når cellen deler sig. Centromerene spiller en central roller under meiosen og mitosen. På samme måde spiller transposonernes yderste ender telomererne en vigtig rolle for at stabilisere kromosomerne og regulerer derved cellens levetid. Livet igennem bliver telomererne kortere, men når der dannes kønsceller bliver de lange igen. I dag forskes der i at forlænge telomererne, da dette måske vil kunne give en længere levetid.

Jorden: The connection between plate tectonics, hydrothermal geochemistry and reduction of simple carbon and nitrogen compounds has shown to be very suitable for abiotic organic chemistry. The best location where such processes could occur would be at convergent margins during the early phases of subduction of oceanic plates.

Venus, with an average surface temperature of 500°C and a steamy atmosphere, is unable to sustain life at its surface. Mars, with an average surface temperature of −60°C and a thin toxic atmosphere, provides a hostile surface environment, but may harbour life in the subsurface.

Carbon, and molecules made from it, have already been observed in the early Universe. During cosmic time, many galaxies undergo intense periods of star formation, during which heavy elements like carbon, oxygen, nitrogen, silicon and iron are produced. Also, many complex molecules, from carbon monoxide to polycyclic aromatic hydrocarbons, are detected in these systems, like they are for our own Galaxy. Interstellar molecular clouds and circumstellar envelopes are factories of complex molecular synthesis. A surprisingly high number of molecules that are used in contemporary biochemistry on the Earth are found in the interstellar medium, planetary atmospheres and surfaces, comets, asteroids and meteorites and interplanetary dust particles. Large quantities of extra-terrestrial material were delivered via comets and asteroids to young planetary surfaces during the heavy bombardment phase. Monitoring the formation and evolution of organic matter in space is crucial in order to determine the prebiotic reservoirs available to the early Earth. It is equally important to reveal abiotic routes to prebiotic molecules in the Earth environments. Materials from both carbon sources (extra-terrestrial and endogenous) may have contributed to biochemical pathways on the Earth leading to life’s origin. The research avenues discussed also guide us to extend our knowledge to other habitable worlds.

  • In Diffuse interstellar clouds: A variety of small molecules, including CO, CH, CN, OH, C2, C3 and others, are observed [41]. Gaseous PAHs are highly abundant. Carbonaceous grains composed of macromolecular aromatic networks
  • the protoplanetary disks of AA Tauri possess a rich molecular emission spectrum in the mid-infrared, indicating a high abundance of simple organic molecules (HCN, C2H2 and CO2)

Merkur - Permanently shadowed craters near Mercury’s poles have temperatures less than -280F (-173C), and water ice is stable on their dark inner surfaces. Some of the polar ice is covered by a mysterious dark organic material that researchers still do not understand.

Tarmfloraens typiske eksempler redigér

Tarmfloraen består af mange forskellige arter, og ved analyser er der identificeret ca. 2000 arter, hvoraf et menneske har ca. 500 forskellige arter. Nogle af tarmfloraens typiske eksempler er

Enterobakterier:

Enterotyper redigér

Menneskets tarmflora kan stort set inddeles i tre enterotyper[2][3]

Type 1 er udpræget hos vesterlændinge der spiser meget protein og dyrisk fedt, hvorimod Type 3 er udpræget hos mennesker der spiser fiberrig kost med kulhydrater.[4]

Enterotyper kan have betydning for en persons sygdomsrisiko eller respons overfor antibiotika og andre farmaka[5]

Thapsigargin redigér

Thapsigargin inhibits Ca2+-transporting ATPase mediated uptake of calcium ions into sarcoplasmic reticulum.

Kemikere overgår naturen Dyreforsøg har vist, at plantestoffet thapsigargin kan anvendes til udvikling af medicin mod prostatakræft. Nu er det lykkedes at syntetisere et stof, som slår kræftceller ihjel ti gange mere effektivt end naturstoffet. Af Søren Brøgger Christensen, Helmer Søhoel og Tommy Liljefors. Fra Lægemiddelforskning 2005 Udgangspunktet for vor kemiske bedrift er naturstoffet thapsigargin, som er en meget kraftig hæmmer af en intracellulær calciumpumpe (SERCA). Når pumpen hæmmes, kan cellen ikke opretholde calciumbalancen og må dø. [15]
