The shape of the nucleic acid molecule translated:

The quality of the mRNA/+RNA sequence:
  only_IRES_fragment
The mRNA/+RNA description: 
In vitro T7 transcript used for structure probing experiments of ELG1 IRES. Transcription was done from PCR
template, prepared from pBiCELG1 vector using ELG1 forward primer with built-in T7 promoter sequence
(taatacgactcactatagggACTTTTGGTGGGCATTTA) and ELG1 reverse primer (cctcgagCTGGGCGGGGAATA).
The mRNA/+RNA sequence represented in the +DNA notation:


Warning: mRNA sequence when devoid of trailing 'A's is still not a substring of the plasmid sequence. Is it because an intron is spliced out? Stay calm then. :-)

The name of the plasmid:
pBiCELG1
The name of the promoter used to express this mRNA:
