Chromatin structure: deduced from a minichromosome.
Cells lytically infected with simian virus 40 contain viral DNA in the form of very small chromlosomnes (minichromosomes) segmented into 100-A lengths, each segment containing about 200 base pairs of DNA. This form resembles that of eukaryotic chromnosom1es anid is consistent with the model of chromatin structure proposed recently.
