 There are reports of minicircles that do not have known transcripts, like in the "Amphidinium carterae" chloroplast genome , although these were not found in the "Symbiodinium" sp.Clade C3 chloroplast genome .Minicircle-derived transcripts can be processed in ways not typical of eukaryotes, including the addition of a 3' poly(U) tail , as opposed to the typical poly(A) tail derived from polyadenylation of eukaryotic transcripts.
