Organic maturation

In eukaryotic cells, the initial mRNA copy contains homologues of both the intron and exon regions. The intron regions are then removed by enzymes located in the nucleus of the cell. Further enzymes splice the exon regions together to form the active mRNA molecules. In both groups of organisms, mature mRNA molecules then pass out of the nucleus into the cytoplasm. 

Kidney development can be used again here to illustrate the kinds of events that occur during organ maturation, which takes place during fetal and postnatal development. While the induction of the organ and formation of its basic structure are initiated in the embryonic period, differentiation of the nephrons is not complete until term in humans, and not until the 2nd week postnatally in rodents.

Functional Development of the Fetus The fetal organs mature during the third trimester but not at the same rate. This section reviews the lung, liver, kidneys, and blood development of the fetus.

Our algorithm for fitting the kinetic parameters E,-, Aj, and X,- uses the total time-temperature history of the source rock sample inferred from the level of organic maturation (solid line in Fig. 6.8b) and from open-system pyrolysis in which temperatures change linearly at rates of 5,15, and 30 C mm, ranging from 300 to 600 °C. For this purpose, the time integrals m Eqs. 6.8 and 6.9 are divided into two parts ...
