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>
Paleontologists can identify organisms that may be ancient relatives of those living today. By looking at fossils they can also suggest how these organisms lived together in an ancient habitat. Few organisms become fossilized because the circumstances that an organism has to be in is very specific.
