To examine the effect of nucleosomes on in vitro transcription, purified chicken erythrocyte core histones and plasmid DNA bearing the Xenopus 5S RNA gene were assembled into nucleosomes and used as templates for transcription in a Xenopus oocyte nuclear extract.
(it could squeeze 100kms out of a liter of fuel) Soon Ducati started bulding a frame to the engine and thus the first official Ducati motorcycle was born.
