COMPARATIVE BANDING PATTERN ANALYSES IN HUMAN CHROMOSOMES INDUCED BY UREA AND TRYPSIN TREATMENTS

Abstract

The present study was undertaken to compare the banding patterns of human chromosomes produced by trypsin and urea treatment techniques. Banding patterns produced by these two techniques appeared to be essentially the same and specific in each pair of homologues. These patterns also enabled the recognition of specific segments of all individual human chromosomes. From the banding pattern produced by the two techniques a diagram of the pattern was proposed by a slight modification from our previous presentation (Shiraishi and Yosida 1972).
