The quality of the mRNA/+RNA sequence:
  hopefully_full-length_mRNA
The mRNA/+RNA description: 
Putative in vivo CMV promoter-derived transcript produced from bicistronic plasmid pbetaGAL/rc_myc/CAT which
comprises beta galactosidase and chloramphenicol acetyltransferase as the first and the second cistron
respectively and the part of human c-myc 5' UTR (nt from +2 to nt -350 of the original sequence) mRNA
cloned between them in reverse complement orientation.
The sequence ends at its 3'-end right after the poly(A) signal from BGH mRNA and thus the 3'-UTR might be
slightly wrong.
