  • (19) In earlier studies with the SV40-transformed hamster cell line Elona two different types of DNA amplification could be identified: (i) Bidirectional overreplication of chromosomally integrated SV40 DNA expanding into the flanking cellular sequences ("onion skin" type) and (ii) highly efficient synthesis of extremely large head-to-tail concatemers containing exclusively SV40 DNA ("rolling circle" type).
  • (20) In addition, the transcriptional behaviour of this tRNALeuCUG gene in various in vitro systems is described and it seems that, although the gene is transcribed in all test systems, the very A + T-rich 5'-flanking sequence of this particular gene may be somewhat inhibitory to transcription in vitro.

Lumbar


Definition:
