A formula is derived to enable the calculation of the true height of an object, such as a shadowed latex bead, from electron micrographs. Knowing only the angle of shadowing and the length of the evaporated shadow, and by substituting these values in the derived formula, a microcomputer may be progr

โฆ Synopsis
An Applesoft BASIC program is presented which allows one to readily graph the secondary struclhre of a protein on the basis of information derived from its amino acid sequence. This applies the Chou/Fasman rutes of predictions to the a-helix, fl-sheet and coil conformational parameters. The program produces a first approximation and provides the additional feature which permits specific modification in the plotted structure. These modifications produce a plot comparable to the existing data obtained from X-ray crystallography and manual computations.

Subjectivity in selecting random grid squares for routine quantitative analysis can be circumvented through a combination of finder grids and a computer program. The simple BASIC program described in this paper generates a list of random grid-square numbers, which are sequentially analyzed. The conc
The possibilities of using a genetic algorithm for the prediction of RNA secondary structure were investigated. The algorithm, using the procedure of stepwise selection of the most fit structures (similarly to natural evolution), allows different models of fitness or driving forces determining RNA s
