DNA is found in the nucleus of eukaryotic cells and the ribosomes, the location where proteins are made, are found out in the cy
Reika [66]

Answer:

See the answer below

Explanation:

<em>The DNA of eukaryotic organisms being present in the nucleus while the protein-synthesizing organelle, the ribosome being present in the cytoplasm poses a spatial problem. It means that transcribed DNAs (messenger RNA) in the nucleus would have to somehow be transported to the ribosome in order for the cell to successfully synthesize proteins.</em>

The problem of transporting the messenger RNA is solved by two features of the cell:

  • The presence of pores in the nuclear envelop
  • The presence of transport proteins in the nucleus

<u>The mRNA binds to the transport proteins to form mRNA-protein complexes and is transported through the nuclear pores, often with the assistance of ATP. </u>
