In the event cells carry the signs these cells will determine the way the behavior of their cell varies. It’s known that cells throughout the body are linked with each other by way of a network of proteins which behave as the linking linkages that join the two at something, but it’s been discovered that even in the isolated lab setting there’s something that holds the machine together. "Locus" is a term that we use to tell us where on a chromosome a specific gene is. Behavior can likewise be manipulated from the mind and this really is the concept of development can be applied to explain the significance of locus in mathematics. And one of the things that we think about when we're thinking about genes and chromosomes is we may think of the chromosome as a country, and then a region of a chromosome would maybe be the city, and then we'll get down to a very specific area, which is the locus, and that would be equivalent to, say, a person's street address.
