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.

Assume that you are trying to insert a gene into a plasmid. Someone gives you a preparation of genomic DNA that has been cut with restriction enzyme X. The gene you wish to insert has sites on both ends for cutting by restriction enzyme Y. You have a plasmid with a single site for Y, but not for X. Your strategy should be to

Following statements are regarding to double fertilization in angiosperms.

A. One sperm cell fuses with the egg cell to produce the zygote that will develop into the new embryonic plant.

B. The second sperm cell fuses with the usually binucleate central cell, giving rise to the

endosperm, the tissue that nourishes the developing embryo. This second event is not “true” fertilization in the sense of male and female gametes undergoing fusion.

C. The second sperm cell fuses with the usually binucleate central cell, giving rise to the

endosperm, the tissue that nourishes the developing embryo. This second event is “true” fertilization in the sense of male and female gametes undergoing fusion.

D. During fertilization in angiosperm, when the sperm cells are released, the egg undergoes a flux of Ca2+. Then, chemicals released from the egg appear to make the sperm competent for cell fusion.
