(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.
