And curious as to how widespread this phenomenon might be, the researchers looked for protein families with nearly identical members that are encoded by different genes and had significant variations in
ribosome density across the family.
Getting at a mechanism for how DNA sequence could influence protein function, the researchers found that
ribosomes density on β - actin RNA is more than a thousand times higher than on γ - actin RNA, and indeed all six actin genes had differences in ribosome density.

Thus, at higher temperatures, eukaryotic phytoplankton seem to require a lower
density of
ribosomes to produce the required amounts of cellular protein.
