Further studies on phosphorylation and the thiol-disulphide ratio of histones in growth and development.

摘要: 1. The proportion of thiol groups in the total thiol+disulphide histone extracts from fertilized eggs Echinus and Psammechinus was increased during periods structural alterations nucleus. 2. probable start DNA synthesis coincided with maximum content. 3. Histone rat liver regenerating were predominantly form no significant variations could be detected first 30hr. after partial hepatectomy. 4. An assay system developed to follow phosphorylation believed associated arginine-rich F3. Phosphorylation by 50% at 1 2hr. phosphate content also period synthesis. 5. found 1hr. hepatectomy not prevented actinomycin or prior irradiation. 6. F1 very high livers foetal rats declined neonatal similarly decline
