THE NUCLEOLUS OF PARACENTROTUS LIVIDUS DURING THE DEVELOPMENT IN THE PRESENCE OF ACTINOMYCIN D.

Botte L , DE Vincentiis M , Scippa S .


Abstract
An ultrastructural study of the nucleolus of embryos of Paracentrotus lividus was carried out after treatment with Actinomycin D. It was shown that the fibrillar component of the nucleolus persists in the embryos treated with Actinomycin D in the mesenchyme blastula stage and fixed 24 and 48 hr after fertilization. The results are discussed in relation to the synthesis of RNA.
