being sure that the paper does not touch the sides of the beaker‚ and then topped. After the eluting solution has risen to within two centimeters of the top of the filter paper‚ the paper was removed from the beaker‚ dried‚ and was stained with a staining reagent solution containing potassium ferrocyanide and potassium iodide. This reagent forms colored precipitates or reaction products with many cations‚ including all of those used in this experiment. The distance of which the spots moved were determined

vannah Sanchez Pre-Assignment #2 1. Describe three patterns of chromosomal breakage and rearrangement. a. Three patterns of chromosomal breakage and rearrangement are deletion‚ balanced translocation‚ and isochromosomal translocation. Deletion is when part of a chromosome is lost affects its length and genetic composition. Translocation is when there is a coinciding break in two chromosomes in different parts resulting in exchange. Balanced translocation is when two homologous chromosomes break

ideas about the nervous system * Reticular theory ( the nervous system consisted of a large network of fused nerve cells) * Neuron theory ( the nervous system consisted of distinct elements or cells * Discovery of staining led to the acceptance of neuron theory. Staining is a chemical technique that caused nerve cells to become colored so they stood out from surrounding tissue * A way of electricity is transmitted in groups of neurons‚ such as the optic nerve.
