Abstract
The comparison of the gel electrophoresis patterns of nuclear and nucleolar matrix proteins reveals marked differences between these structures. The nucleolar matrix contains 5 prominent protein bands (mol.wt.: 8.2; 7.0; 5.6; 4.0 and 3.0 × 10 4 ) which are not found in nuclei. It is suggested that the nucleolar matrix has a distinct structure participating in selective interactions.Keywords
