Cajal bodies

Cajal bodies
compact intranuclear structures, up to 10 per cell, about 1 μm in diameter and resembling balls of tangled thread on electron microscopy; they contain factors involved in messenger RNA processing and a number of nucleolar proteins and may be involved in regulation of some small nuclear RNA genes. Called also coiled b's.
