WebNational Center for Biotechnology Information WebAt low resolution, bands are classified using the nomenclature [chromosome][arm][band], where band is a single digit. Examples of bands on chromosome 3 include 3p2, 3p1, cen, 3q1, and 3q2. At a finer resolution, some of the bands are subdivided into sub-bands, adding a second digit to the band number, e.g. 3p26. This resolution produces about ...
