Before And After

Olfactory receptors (ORs) are responsible for recognition of odor molecules. The deoxyribonucleic acid (DNA) sequences of these receptors are severely affected by local mutations. Therefore, to study the changes among affected and non-affected ORs, the authors attempted to use unsupervised learning (clustering) algorithm. In this paper, they have used a scaled fuzzy graph model for clustering to study the changes before and after the local mutation on DNA sequences of ORs. Their simulation study at the fractional dimensional level confirms its accuracy.

Abstract The problem of DNA sequence assembly is well known for its high complexity. Experimental errors of di erent kinds present in data and huge sizes of the problem instances make this problem very hard to solve. In order to deal with such data, advanced efficient heuristics must be constructed. Here, we propose a new approach to the sequence assembly problem, modeled as the problem of searching for paths in an acyclic digraph. Since the graph representing an assembly instance is not acyclic in general, it is heuristically transformed into the acyclic form. This approach reduces the time of computations significantly and allows to maintain high quality of produced solutions.

Fluorescent Spot

Using fluorescence in situ hybridization (FISH), the positions of DNA sequences can be discretely marked with a fluorescent spot. The efficiency of marking DNA sequences of the size cloned in cosmids is 90-95%, and the fluorescent spots produced after FISH are ≈0.3 μm in diameter. Sites of two sequences can be distinguished using two-color FISH. Different reporter molecules, such as biotin or digoxigenin, are incorporated into DNA sequence probes by nick translation. These reporter molecules are labeled after hybridization with different fluorochromes, e.g., FITC and Texas Red. The development of dual band pass filters (Chromatechnology) allows these fluorochromes to be photographed simultaneously without registration shift.

This essay examines the convergence of conceptualist poetics with evolutionary code as a form of ‘becoming alien’. The focus is Christian Bök's The Xenotext project: an attempt at translating a ‘short verse about language and genetics’, using a chemical alphabet, into a DNA sequence implanted into the genome of a polyextremophile bacterium capable of enduring conditions in outerspace. Bök describes the project as, ‘in effect, engineering a life-form so that it becomes not only a durable archive for storing a poem, but also as an operant machine for writing a poem – one that can persist on the planet until the sun itself explodes …’. The concrete, constraint-based character of Bök's project evokes a mode of writing between posthumanist aesthetics and a positivist grammatology by turns deconstructive and itself requiring of deconstruction.
