The diagram shows a cross section of a eukaryotic cell. How do the nucleus and ribosomes work together? a The ribosomes perform chemical reactions that supply the nucleus with needed nutrients. b The nucleus creates proteins and lipids that the ribosomes then transport to other organelles. c The nucleus sorts and distributes the genetic information it receives from the ribosomes. d The ribosomes build proteins based on the genetic instructions they receive from the nucleus.

Answer 1

The correct option is d: The ribosomes build proteins based on the genetic instructions they receive from the nucleus.

In eukaryotic cells, the nucleus contains the cell's genetic material (DNA), which provides the instructions for making proteins. These instructions are transcribed into messenger RNA (mRNA) in the nucleus, which then travels to the ribosomes—either free-floating in the cytoplasm or attached to the endoplasmic reticulum—where the ribosomes translate the mRNA into proteins. This process illustrates how the nucleus and ribosomes work together to synthesize proteins.
