Abstract
Firket and Verly recently presented1 some results on the labelling of chromosomal deoxyribonucleic acid in chick fibroblast cells with tritiated thymidine. One of their conclusions is that their results support the hypothesis of the equal distribution of labelled, and hence newly synthesized, deoxyribonucleic acid between sister anaphase and telophase chromosome sets and contradict an earlier observation by Mazia and me2 that this distribution may be decidedly unequal.
