Description

Cytodifferentiation and Macromolecular Synthesis focuses on research on biosynthesis, structure, and morphology of cells. The book first discusses cytodifferentiation and macromolecular synthesis and genetic control of protein structure. The relationship of amino acid substitutions to the genetic code; comparison of gene and protein alterations; and suppressor mutations are described. The text also looks at genetic repression, allosteric inhibition, and cellular differentiation; epigenetic control of protein synthesis in cells; quantitative studies of protein synthesis in embryonic tissues; and chromosomes and cytodifferentiation. The book also discusses the morphological and chemical differentiation of plastids. The effect of light on plastid development; structure of mature chloroplast; morphological changes in the development of proplastid to the chloroplast; and inheritable factors that control plastids are described. The text also focuses on the collagen system, mechanisms of elongation, and tissue interaction and metabolic responses. The book is a valuable reference for readers wanting to conduct research on the complex nature of cells.
