From: Molecular cytogenetic analysis of the karyotype of the European Atlantic sturgeon, Acipenser sturio

Diagram of the 5S rDNA cluster in Acipenser sturio and location of primers used for PCR amplification and sequencing (5SF–5SR and NTSF–NTSR). Fragment A was used as the 5S probe for in situ hybridization. Alignment of fragments A and B yielded the complete 221-bp sequence of the 5S gene. Primer sequences (or their complementary sequences) are reported in lower case.
