Respuesta :
In the background section, it is noted that inhibition of protein synthesis blocks cell division in sea urchins. This observation implies that: new proteins must be made for cell division to occur.
The correct option is e.
The radial holoblastic cleavage is seen in sea urchins. Both the first and second cleavages are meridianal and parallel to one another. In other words, both the animal and vegetable poles are cut by the cleavage furrows.
A substance known as a protein synthesis inhibitor prevents or delays cell growth or proliferation by interfering with the procedures that directly result in the production of new proteins.
Proteins called cell-cycle proteins are involved in the control and upkeep of the cell cycle in eukaryotic cells. These comprise kinases and cyclins that control transitions between the three stages of the cell cycle, interphase, mitosis, and cytokinesis, which lead to cell replication and division.
The complete question is:
In the background section, it is noted that inhibition of protein synthesis blocks cell division in sea urchins. this observation implies that:
a. all of the components for cell division are always present in the cell for cell division to occur.
b. translation is not required for cell division to occur.
c. None of the answers are correct
d. proteins are not required for cell division to occur
e. new proteins must be made for cell division to occur.
