title: On the structure of chromosome ends as revealed by trypsin treatment of Locusta migratoria chromosomes.
abstract: Anaphase chromosomes exhibit two longitudinal structures which are connected at their ends in a U-shaped closed configuration. The U-shaped ends might be part of the chromosome characterized by a relatively dense condensation of chromosomal material or part of the loop-like structure of the chromosome per se.
