Sizes of chromosome loops and hnRNA molecules in oocytes of amphibia of different genome sizes

Please always quote using this URN: urn:nbn:de:bvb:20-opus-33094
  • The lengths of lampbrush chromosome loops and their tran scription units show a positive correlation with genome size in oocytes of amphibia with different C values. However, there is no such correlation with contour lengths of hnRNA molecu les isolated from these oocytes. These results indi cate th at more ON A sequences are transcribed in amphibia of higher C value , but that processing of RNA transc ripts occurs while they are still attached to the chromosomes as nascent ribonucleoprotein fibrils.
