Organisms with alternative genetic codes resolve unassigned codons via mistranslation and ribosomal rescue.

abstract：:Genomic rearrangements associated with speciation often result in variation in chromosome number among closely related species. Malassezia species show variable karyotypes ranging between six and nine chromosomes. Here, we experimentally identified all eight centromeres in M. sympodialis as 3-5-kb long kinetochore-bou...
