IRESite record type: plasmid_with_promoter_and_putative_IRES_translationally_characterized
The shape of the nucleic acid molecule translated: linear
The quality of the mRNA/+RNA sequence: our_best_guess
The mRNA/+RNA description:
Putative spliced in vivo SV40 promoter-derived transcript produced from bicistronic plasmid pRL which
comprises renilla and firefly luciferases as the first and the second cistron, respectively and the 5' UTR (nt
8 to nt 300) plus first 27 bp from human n-myc mRNA.
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. :-)
