The telomeres of Streptomyces chromosomes contain conserved palindromic sequences with potential to form complex secondary structures

The chromosomes of the Gram‐positive soil bacteria Streptomyces are linear DNA molecules, usually of about 8 Mb, containing a centrally located origin of replication and covalently bound terminal proteins (which are presumably involved in the completion of replication of the telomeres). The ends of the chromosomes contain inverted repeats of variable lengths. The terminal segments of five Streptomyces chromosomes and plasmids were cloned and...
