[ARS-activity of a DNA fragment from Bombyx mori in Saccharomyces cerevisiae cells].

A previously cloned autonomous transgene (pr8a) of silkworm Bombyx mori inherited without changes in the structure was used to clarify the activity of its ARS in yeast cells. ARS of pr8a was also shown to maintain autonomous replication of hybrid plasmids in yeast cells. The same was true for its central 2.
