Mature mRNA transcripts (sense strand) from eukaryotic cells can be purified and then reverse transcribed, with the assistance of a reverse transcriptase enzyme (from Moloney murine leukemia virus, MMLV), into complementary DNAs (cDNAs) that will anneal with the mRNA transcripts by Watson-Crick base pairing to give anti-parallel DNA/RNA duplexes or double helices. The poly(A) tail in each mature mRNA transcript is actually a usefiil handle for each reverse transcriptase reaction. Thereafter, DNA/RNA duplexes must be broken down with the assistance ofRNAse enzymes (specific for the hydrolysis of RNA phospho diester links) and a sense strand of DNA constructed instead on each cDNA single strand so that equivalent, more stable antiparallel DNA/DNA duplexes are generated instead, with the assistance of a DNA polymerase enzyme. In this instance, the poly(T) tail in each cDNA molecule turns out to be important for the DNA polymerase reaction ... [Pg.144]

The presence of the poly-A tail has been very fortuitous for researchers. By designing an affinity chromatography column (Chapters 5 and 13) with a poly-T tail (or poly[d(T)] tail), the isolation of mRNA from a cell lysate... [Pg.320]

The cDNA prepared from mRNA would have a long poly(T) tail, unlike genomic DNA. Remember that the poly(A) tail is added to the 3 end of mammalian mRNA and that there is no counterpart on DNA. A second striking difference would be that the cDNA would contain no intervening sequences (introns) and would therefore be much shorter... [Pg.511]
