Activity of DNA-dependent RNA polymerases in rabbit mammary gland during lactogenesis (original) (raw)

This research investigates the activity of DNA-dependent RNA polymerases in the rabbit mammary gland during lactogenesis. It examines the contributions of polymerases A and B to total RNA synthesis around the time of parturition, comparing activities in nuclei isolated during different physiological states (early lactation vs late pregnancy). Findings indicate that both polymerases play significant roles in RNA synthesis, with distinct contributions observed at varying stages of mammary gland development.
