After the investigations on several ecological factors of growth and spores release of Enteromorpha prolifera ( Mller ) J.

Preliminary study on maturation and spore release of Gloiopeltis furcata and G. tenax in indoor cultivation;

At first,the blood of right atrium flows ventrally into the cavum pulmonale through cavum ateriae with "quantum release",then the pressure risng in the left atrium drive dorsally the blood to open the ostium atrioventriculare and flows into the cavum ateriae-venosum,there is only a few mixed blood in the interface of de-and oxygenated blood.

This process is maintained by two classes of peptide release factors (RF1/RF2,RF3 and eRF1,eRF3 in prokaryotes and eukaryotes,respectively).

It is not a simple process, not only some factors affect efficiency of translation termination, such as release factor, context of stop codon and trans-acting factors, but also translation termination itself plays as a control point of regulation of gene expression.
