Transcription of three actin genes and a repeated sequence in isolated nuclei of sea urchin embryos.

abstract：:In mammals, sex is determined in the bipotential embryonic gonad by a balanced network of gene actions which when altered causes disorders of sexual development (DSD, formerly known as intersex). In the XY gonad, presumptive Sertoli cells begin to differentiate when SRY up-regulates SOX9, which in turn activates FGF9 ...
