The Biochemistry of Development

Book excerpt: The Biochemistry of Development focuses on advances in chemical embryology. The book first discusses gametogenesis, including the processes of oogenesis and spermatogenesis. The text describes fertilization and related aspects, such as physical, morphological, and metabolic changes during fertilization. The selection also underscores the process of cleavage. Concerns include morphology and cytochemistry of dividing eggs; importance of nucleic acids and proteins; formation of the furrow; and biochemistry of cleavage. The text also looks at the chemical embryology of invertebrate eggs. Examinations are done on the eggs of worms, mollusks, sea urchins, and ascidians. The book also evaluates the chemical embryology of vertebrate eggs. RNA and protein metabolism of intact eggs; chemical nature of inducing substances; and physical properties of inducing agents are underscored. The text also offers information on the biochemistry of differentiation and the biochemical interactions between the nucleus and the cytoplasm during morphogenesis. The selection is highly recommended for readers wanting to study chemical embryology.
