Cell cycle time and possible early DNA replication in C-band regions in the domestic pig (Sus scrofa) lymphocytes.
Dynamic cell replication studies on peripheric blood lymphocytes cultured from the domestic pig (Sus scrofa) were performed. Replication started after 18-24 hr in culture and the cell cycle time was about 8-10 hr. Chromosomes from cells at first division showed C-banded-like regions. This finding suggests the occurrence of early DNA replication zones within the constitutive heterochromatin of the pig chromosomes.
