Abstract
When fragmented, native T4 DNA served as primer for the E. coli RNA polymerase, over 90 per cent of the synthetic RNA had nucleotide sequences in common with those found in T4 RNA synthesized in vivo. If indeed only one strand of the DNA molecule is transcribed in vivo, then it may be concluded that the same strand was utilized in vitro. However, the strand selection mechanism was destroyed by heat denaturation of the primer T4 DNA, resulting in nearly equal copying of both strands. Sonication of primer T4 DNA also caused a partial loss of strand selectivity.
