✦ Synopsis
Abstract
DNA polymerase activity increases in full‐grown oocytes of Xenopus laevis during in vitro progesterone‐induced maturation. This increase in inhibited by cycloheximide. The presence of the oocyte's nucleus (germinal vesicle) seems essential for the induction of this increase: in previously enucleated oocytes, the level of DNA polymerase activity does not change during progesterone treatment.
Furthermore, a new form of DNA polymerase is detectable by DEAE chromatography in in vitro matured oocytes.
