The minimum legth of a codon could be two. If it was only one of the 6 nitrogeneous bases in a codon, we'd only have 6 possible amino acids. If we have, though, a combination of two amino acids out of the 6 nitrogeneous bases, we would have then 36 possible combinations (6 possibilities for the first position × 6 possibilities for the second position) that would allow the existence of the 20 different amino acids.
In the human case, for example, with only 4 nitrogeneous bases, a combination of two amino acids would be insufficient (4×4=16) for the 20 amino acids.
Upwelling is a process in which the deep and cold water rises to the water surface and not sea surface. This process plays an important role in maintaining balance in our ecosystem as it boost the marine productivity by washing the nutrients from deeper waters to the photic layer where photosynthesis is promoted.
