Outgrowing meiosis
F ertilization triggers an upheaval in the egg, including a switch from meiosis to mitosis as the method of cell division. Courtois et al. show that this transition is gradual and isn’t complete until after the embryo’s 8th division (1). Meiosis and mitosis differ in several ways. Unlike the bipolar mitotic spindle that is anchored by a centrosome at either end, the meiotic spindle starts out w...
متن کاملResporulation of outgrowing Bacillus subtilis spores.
Germinated spores of Bacillus subtilis were incubated in outgrowth medium and tested periodically for capacity to sporulate when suspended in sporulation medium. Concurrent measurements were made of deoxyribonucleic acid (DNA) content and numbers of cell division septa and nucleoids. Sporulation potential is shown to reach a peak at about 110 min at which time the chromosomes are probably well ...
متن کاملOutgrowing Resource Dependence: Theory and Evidence
Many policy makers are concerned about dependence on resource exports. This paper examines four changes that can potentially reduce this dependence: (i) accumulation of capital and skills; (ii) changes in protection policy, particularly reductions in the burden of protection on exporters; (iii) differential rates of technical change; and (iv) declines in transport costs. Developing countries as...
متن کاملThe Deeper Work of Executive Development: Outgrowing Sensitivities
Often overlooked in management theory and education, how leaders function in an intrapersonal sense—the “inner game” of leadership—is pivotal. We develop this idea in a specific application by describing how psychological wounds sensitize executives to be anxious about getting hurt again. These vigilant and unconscious concerns distort perceptions of organizational reality and lead to unnecessa...
متن کاملAxon guidance of outgrowing corticospinal fibres in the rat.
This review is concerned with the development of the rat corticospinal tract (CST). The CST is a long descending central pathway, restricted to mammals, which is involved both in motor and sensory control. The rat CST is a very useful model in experimental research on the development of fibre systems in mammals because of its postnatal outgrowth throughout the spinal cord as well as its experim...
