Brdu replication bands in the anguilliform fish Echelus myrus
Abstract
High-resolution replication banding patterns have been obtained in prometaphase and metaphase chromosomes of the anguilliform fish species Echelus myrus by treating kidney cell cultures with 5-bromodeoxyuridine during the mid-late synthesis phase. The results show the superiority of the in vitro technique in obtaining a higher number of bands which permit an accurate identification of all chromosome pairs. Different replication patterns were compared with C-bands and silver-stained nucleolus organizer regions, providing information on the replication order of different chromatin regions.
