However, the structure of chromatin also appears to serve a second, possibly more important role, in that it gives eukaryotic cells the capability to exert complex levels of control over gene ...

What have we learned about RNA structure and function so ... In comparison, eukaryotic cells contain two types of rRNA genes that give rise to four rRNA species: the 28S, 5.8S, 5S, and 18S rRNAs.

This simplified structure allows for rapid transcription and translation, enabling prokaryotes to respond quickly to environmental changes. In contrast, in eukaryotic genes, the primary RNA ...

Their cell structure is simpler than the cells of animals ... Genetic material DNA in a nucleus, plasmids are found in a few simple eukaryotic organisms. DNA is a single molecule, found free ...
