Question

in the background section, it is noted that inhibition of protein synthesis blocks cell division in sea urchins. this observation implies that: all of the components for cell division are always present in the cell for cell division to occur. proteins are not required for cell division to occur. new proteins must be made for cell division to occur. translation is not required for cell division to occur. none of the other answer options is correct.

Answer 1

The given observation in sea urchins implies that new proteins should be synthesized so that the process of cell division can take place.

Sea urchins belong to the phylum Echinodermata. These organisms are mostly preferred by the embryologists for studying the process of cell division because they produce gametes in abundant amount which can be obtained easily. The sea urchins produce eggs as well as embryos which are transparent in nature.

Early cell divisions in sea urchins are fast-paced. Radial holoblastic cleavage can be observed in sea urchins. The proteins that are manufactured during cleavage use mRNAs present in the cytoplasm given by the female parent.
