According to this model, Which of the following statements are correct?

#Unit 5. Developmental Biology
  1. SKN-1 is a maternal gene which activates GATA transcription factors in the EMS cell.
  2. The POP-1 signal prevents MED-1,2 proteins from activating the ectodermal transcription factors and instead activates the tbx-35 gene.
  3. The TBX-35 transcription factor activates mesodermal genes in the MS cell, including pha-4 in the muscles and hlh-1 in pharynx.
  4. TBX-35 also inhibits pal-1 gene expression, thereby do not inhibit the MS cell from acquiring the C- blastomere fates.
