Non-Random Distribution of Alu-Family DNA Repeats in Human Chromosomes,omoter for RNA polymerase III, which is active . (Perez-Stable et al., 1984) but is silent in HeLa cells . (Poulson and Schmid, 1986). We have studied long-range distribution of AFRs in human chromosomes using tritium-labeled (Filatov et al., 1984; Filatov et al., 1987; Filatov et al., 1988) and bio

Isolation and Properties of a Novel Specific Fraction of Chromosomal DNA from Human, , and Plant Ce eukaryotic genomes (Schwartz and Cantor, 1984). PFG electrophoresis is currently unable to separate much longer chromosomes. We have used PFG electrophoresis of intact undigested DNA from human, . and plant cells and found a resolvable DNA fraction. The procedure used allows one to isolate DNA . by

Ribosomal Protein Genes in , Organization, Structure and Identification of the cis-Element Responsis ribosomal proteins (r-proteins). In particular about 70 different r-proteins are coordinately synthesized during . oogenesis and embryo development (Pierandei-Amaldi et al. 1982). A number of different experimental approaches (reviewed by Amaldi et al. 1989) have shown that the control of r-protei
