1. Models of spreading of TCAT-like elements based on (A) retrotransposition of CR-3_TCa element.
Models of spreading of TCAT-like elements based on (A) retrotransposition of CR-3_TCa element. CR1-3_TCa was inserted within TCAST satellite array and through recombination has acquired a part of TCAST sequence, which could act as a promoter and become a new functional 5′UTR. Subsequent retrotransposition of CR1-3_TCa could explain the dispersion of TCAST within the euchromatin. (B) Rolling circle replication of TCAST satellite DNA sequences excised from their heterochromatin loci via intrastrand recombination, followed by reintegration into different genome locations by homologous recombination.
