abstract：:Chromosomal RNA was isolated from several rat tissues by a new technique. It is shown by RNA-DNA hybridization that each tissue contains a distinct population of chromosomal RNA sequences. This finding is compatible with the proposal that chromosomal RNA is involved in the process of gene activation. ...
