Trying to Avoid Your Sister
Connections between chromosomes are essential for their accurate segregation during cell division. In somatic cells dividing by mitosis, newly replicated sister chromatids are connected by cohesin proteins. When the sister chromatids become attached to microtubules emanating from opposite poles of the spindle, cohesins resist the pulling forces and the ensuing tension stabilizes the chromatid–m...
متن کاملTypical Ambiguity: Trying to Have Your Cake
Ambiguity is a property of syntactic expressions which is ubiquitous in all informal languages–natural, scientific and mathematical; the efficient use of language depends to an exceptional extent on this feature. Disambiguation is the process of separating out the possible meanings of ambiguous expressions. Ambiguity is typical if the process of disambiguation can be carried out in some systema...
متن کاملHow to Avoid "Thinking on Your Feet"
The common otion of "thinking on your feet" refers to the ability to quickly make decisions in response to changing situations. Implied in this concept is that reasoning about taking action takes place at (or very near) the time of action. In this note we argue that such a skill is neither practical nor necessary in general. A key research issue concerning approaches to taking time-critical act...
متن کاملHolding your own: establishing sister chromatid cohesion.
Chromosome Segregation and Genome Integrity At cell division, both daughter cells receive only one copy of the parental genome. Not surprisingly, chromatin plays a role at numerous stages to ensure that genome segregation occurs with high fidelity. First, each chromosome is duplicated to produce two identical chromosomes called sister chromatids. Second, sister chromatids become paired, or glue...
متن کاملHow to Avoid Hard Coding Variables in Your Simulation Model
The purpose of this paper is to demonstrate the ability of AutoMOD as a flexible modeling tool. Simulation models of material handling systems like those found in automotive paint shops & assembly systems often require many variables, conveyor speeds, and complex logic. These systems have many different variables associated with them. The most important ones are: conveyor speeds, carrier counts...
