The globin and immunoglobulin multigene families have been used to study the effect of chromosomal organization on the time of gene replication. Some of the genes are late-replicating, providing the first identification of late-replicating sequences that are not highly repetitive. One is a member of the mouse alpha-globin gene family, which consists of(More)
The time of replication during the S phase in a murine erythroleukemia (MEL) cell line was determined for immunoglobulin heavy chain constant region C alpha, C gamma 2b and C mu sequences whose boundaries are defined by EcoR1 restriction endonuclease sites (EcoR1 segments). Logarithmically growing cultures of MEL cells with an S phase of about 7.5 hours(More)
