- One of the most important gene, involved in dorsal—ventral axis determination in Drosophila is dorsal. It codes Dorsal protein which
(1) is taken up into the nuclei of cells and this side will become the ventral side
(2) remains in the cytoplasm of cell and this side will become ventral side.
(3) is taken up into the nuclei of cells and this side will become the dorsal side.
(4) degraded in one side and that will become dorsal sideDuring early embryonic development in Drosophila, the dorsal-ventral axis is established by a gradient of the Dorsal protein, encoded by the dorsal gene. A key feature of this protein is its differential localization: it enters the nuclei of cells on the future ventral side while remaining in the cytoplasm on the dorsal side.
Specifically, the Dorsal protein’s nuclear uptake on the ventral side activates expression of ventral-specific genes responsible for mesoderm formation. Conversely, absence of nuclear Dorsal on the dorsal side allows dorsal-specific genes to be expressed. This gradient of nuclear localization is essential for proper patterning along the dorsal-ventral axis.
A mutation or disruption that alters this pattern affects cell fate and embryonic development accordingly. Thus, the side of the embryo where Dorsal is taken up into the nuclei becomes the ventral side.
Therefore, the correct statement is:
(1) Dorsal protein is taken up into the nuclei of cells and this side will become the ventral side.
Answer: (1) is taken up into the nuclei of cells and this side will become the ventral side

November 13, 2025If nucleaus goes to upeer side that mean this side is dorsal surface and other side is ventral surface
At ventral surface torpido not bind with guruken protein means mirror protein not activate so synthesis of pipe protein .
Dorsal protein + caktus can be cleaved by pelle kinase toll R tube p means phosn of caktus so cactus is degarade and dorsal work as tc f
Dorsal go into nu and develop ventral surface
