Histone gene clusters of the newt notophthalmus are separated by long tracts of satellite DNA

Academic Article


  • The genomic organization of the histone genes of the newt Notophthalmus viridescens is described. Genes for the five proteins are clustered on a 9.0 kb segment of cloned DNA which is part of a homogeneous family of sequences containing 600-800 members per haploid genome. The 9.0 kb histone gene clusters are not adjacent in the genome, but are separated from neighboring clusters by up to 50 kb or more of cluster spacer sequences; some or all of these spacer sequences are members of a predominantly centromeric satellite DNA with a 225 bp repeating unit. © 1981.
