## The nuclear DNA of eukaryotes is organized into a series of loops each topologically anchored by elements of the nuclear matrix. Evidence is reviewed which indicates that the anchorage points of the loops are formed by transcriptionally active genes and that individual loops function as replicons

โฆ Synopsis
Sometimes genes are arranged nonrandomly on the chromosomes of eukaryotes. This review considers instances of gene clusters in which two genes or more are expressed from a single promoter. This includes cases in which a polycistronic pre-mRNA is processed to make monocistronic mRNAs in nematodes, as well as isolated examples of polycistronic mRNAs found in mammals, flies, and perhaps plants.

The past several years have seen remarkable growth in our understanding of the molecular processes underlying fragile X syndrome (FXS). Many studies have provided new insights into the regulation of Fmr1 gene expression and the potential function of its protein product. It is now known that the prom
TGFP is a potent, nontoxic inhibitor of mitogen-induced DNA synthesis in primary cultures of adult rat hepatocytes. Using a cDNA probe, we investigated TGFP gene expression in quiescent, regenerating, and neoplastic liver, and several hepatoma lines by Northern gel analysis. We found that regenerati
