Summary
A human-Chinese hamster hybrid cell line was treated with X-rays and subsequently cloned. In two clones, segregation between three markers assigned to the human A1 chromosome (6-phosphogluconate dehydrogenase, phosphoglucomutase 1 and peptidase C) was found. Chromosome analysis revealed an aberrated human A1 chromosome in both clones. The results suggest the following gene sequence on chromosome A1: 6 PGD, PGM1 (on the short arm), Pep C (on the long arm).
Zusammenfassung
Eine Zell-Linie (Hybride zwischen Zellen vom Menschen und vom Chinesischen Hamster) wurde mit Röntgenstrahlen behandelt und anschließend kloniert. In zwei Klonen wurde eine Aufspaltung bei drei Markern beobachtet, die zum menschlichen A1-Chromosom gehören (6-Phosphogluconat-Dehydrogenase; Phosphoglucomutase 1; Peptidase C). Die Chromosomenanalyse zeigte ein aberrantes menschliches A1-Chromosom in beiden Klonen. Die Ergebnisse legen die folgende Reihenfolge nahe: 6 PGD; PGM1 (auf dem kurzen Arm); Pep C (auf dem langen Arm).
