✦ Synopsis

The time course of replication of the 9 kb ribosomal DNA repeats of synchronized root cells of pea was followed by two-dimensional gel electrophoresis. The temporal order of appearance of single-stranded replication intermediates shows that replication begins within the subrepeats located in the intergenic spacer region about 1.5 kb downstream from the 3' end of the 25S gene. Hybridization to specific probes indicated that this location is identical to that established earlier by a different method.

The 80S ribosome of Schizosaccharomyces pombe contains 93 proteins as determined by twodimensional electrophoresis on polyacrylamide gels. Of these, 76 are basic and 17 are acidic at pH 8.7. 38 proteins could be assigned unambiguously to the large sub-unit and 19 to the small. 67 proteins were extra
