The mRNA/+RNA description: 
Putative spliced in vivo SV40 promoter-derived transcript produced from bicistronic plasmid pstemRL which
comprises renilla and firefly luciferases as the first and the second cistron, respectively and the whole
mouse VEGF 5' UTR (nt from -1014 to nt +3 of the original sequence) mRNA with a hairpin in front of the first
cistron.
The sequence ends at its 3'-end right after the poly(A) signal from SV40 mRNA and thus the 3'-UTR might be
slightly wrong.
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. :-)
