This paper attempts to compare two biological successions, in general any two successions, analysing the differences between them.
An algorithm was designed based on a metric which enables one to calculate the associated distance between two successions and, based on the distance obtained, the type of mutations which have occurred was approached.
The empirical analysis shows that the transformations caused in the successions have been detected by the metric. Today there are numerous enormously powerful programs able to trawl entire databases and therefore the aim of this paper was not to compare these, but to demonstrate a different way of comparing two given successions.
The paper presents a comparison of two DNA successions having a measure of the degree of similarity between them and their possible mutations.
The metric presented is a generalisation of the Hamming distance in strings of different lengths. The software associated with the metric has made it possible to validate the results obtained.
