First look at what the data look like: head -30 cytoBand.txt chr1 0 2300000 p36. https://divingintogeneticsandgenomics.com/archive/cytogenetic-band-explained/ Thu, 22 Oct 2015 14:32:00 -0700 https://divingintogeneticsandgenomics.com/archive/cytogenetic-band-explained/ This is a review of the basic concept of cytoband in molecular/cell biology. See the original link by Strachan, T. and Read, A.P. 1999. Human Molecular Genetics, 2nd ed. New York: John Wiley & Sons. Each human chromosome has a short arm ("p" for "petit") and long arm ("q" for "queue"), separated by a centromere. The ends of the chromosome are called telomeres. Each chromosome arm is divided into regions, or cytogenetic bands, that can be seen using a microscope and special stains.
