TABLE 1.

Variants found in the 3′NTR poly(A)-tail of poly(A)-containing replicons^a

^aTwenty cDNA clones derived from two separate colonies selected from the pFK5.1_pA57, pFK5.1_pA65, and pFK5.1_C_-5U plates (Fig. 3) were sequenced. Nucleotides different compared to the input selectable replicon RNA are indicated in red. Nucleotides introduced to generate a transcription runoff transcription site (ScaI) are indicated in blue. Clone numbers (#no.) are indicated next to the sequence.
