A comparison of the chromosomes banding pattern after G-and C-staining with the time of DNA reduplication and the degree of chromosome condensation, was carried out using Chinese hamster metaphase chromosomes. Chromosome condensation was studied under 5-bromodeoxyuridine and 5-bromodeoxycytidine treatment. All the chromosomal segments stained with C-technique are also stainable with G-technique, while only some G-positive segments are capable to be C-bands. C-bands are heterochromatic segments characterized by extremely late replication and great delay in condensation under the analog action, while G-bands are segments with earlier labelling and irregular decondensation. The data obtained suggest a close correlation between the capability of chromosomal region of G- and C- staining and the degree of its heterochromatinization. |
