Main articles: Growth hormone 1 and Growth hormone 2. Genes for human growth hormone, known as growth hormone 1 (somatotropin) and growth hormone 2, are localized in the q22-24 region of chromosome 17 and are closely related to human chorionic somatomammotropin (also known as placental lactogen) genes.
The short-run marginal cost (MC) curve will at first decline and then will go up at some point, and will intersect the average total cost and average variable cost curves at their minimum points.
It is clear from the diagram (13.9), that the long run marginal cost curve and the long run average total cost curve show the same behavior as the short run marginal cost curve express with the short run average total cost curve.hen average total cost curve begins to rise, marginal cost curve also rises, passes through the minimum point of the average cost and then rises. The only difference between the short run and long run marginal cost and average cost is that in the short run, the fall and rise of curves LRMC is sharp.
