604Publicado 1978“…A novel view of the eukaryotic cell cycle is taking form as genetic strategies borrowed from investigations of microbial gene regulation and bacteriophage morphogenesis are being applied to the process of cell division. It is a genetic construct in which mutational lesions identify the primary events, thermolabile gene products reveal temporal order, mutant phenotypes yield pathways of causality, and regulatory events are localized within sequences of gene controlled steps.…”

605por Chambers, Robert“…The elongation of the egg during cleavage is possibly produced as a consequence of the mutual pressure of these two growing semisolid masses. 3. The division of the egg into two blastomeres consists essentially in a growth, within the egg, of two masses of material at the expense of the surrounding cytoplasm. …”

609“…Quantitative analysis of the distribution of newly synthesized DNA in postmetaphase stages of the division following the period of label incorporation led to the conclusion that the new DNA is not necessarily equally distributed by the mitotic process and that, therefore, chromosome duplication does not involve the equal partition of parental DNA. …”

611“…Small unilamellar fatty acid vesicles grow when fed with fatty acid micelles and can be forced to divide by extrusion, but this artificial division process results in significant loss of protocell contents during each division cycle. …”

613“…Spatial control of cytokinesis is critical for cell and plant morphology. The plane of cell division is established at G2/M transition and is initially demarcated at the cortex of the cell by the cytoskeletal preprophase band (PPB) and subsequently throughout mitosis by the cortical division zone (CDZ). …”
