Initiation of Chloroplast DNA Replication in ,e have been isolated as covalently closed circular molecules with lengths in the range of 110 to 215 kb. Chloroplasts contain multiple copies of the circular genome (1). Chloroplast DNA can be purified on the basis of either its location within the organelle or its distinct base composition. Nuclear

The Replication of Double-Stranded RNA some ways, these dsRNA genomes are more similar to plasmids than to true viruses. They are noninfectious and are transferred between cells only under conditions of cytoplasmic mixing, such as occurs in mating or other natural or artificial means of cell fusion (10,42). The particles are stably main
