les uv des agents mutagènes


  • Quel est l'effet des UV sur la diversité des phénotypes ?

    10) Indiquez l'effet des UV sur la diversité des phénotypes. Les UV sont donc une source de modification aléatoire du génotype (haut potentiel mutagène) donnant ainsi naissance à de nouveaux phénotypes.
  • Comment les UV modifient la structure de l'ADN ?

    Les UVA n'affectent pas directement l'ADN, mais ils provoquent la formation dans les cellules de radicaux oxygénés comme H2O2 qui sont agressifs vis-à-vis de l'ADN provoquant des ruptures dans les brins d'ADN et aussi la formation de dimères.
  • Quelles sont les agents mutagènes ?

    Les agents mutagènes peuvent modifier (mutation) le matériel génétique (ADN) des cellules des personnes ou des animaux de laboratoire, ce qui entraîne des maladies ou des anomalies chez les générations futures.
  • Les rayons ultra-violets engendrent des mutations. Une mutation peut engendrer un changement de couleur de la levure qui devient blanche. Elle peut aussi atteindre des gènes fondamentaux à la survie de la levure.
