Protein synthesis

RE Sugerido

From the source:
The biosynthesis of proteins involves translation of the information contained in the mRNA into a polypeptide sequence. Each triplet of bases in the mRNA encodes one amino acid. This in an animation of this process.

Isotonic Equilibrium

RE Sugerido

From the source:
Cells continually encounter changes in their external ionic environment and will spontaneously respond by attempting to equalize the concentration of ions on the inside and outside of the cell. This is an interactive animation that addresses this process.
