with the availability of techniques for dna-dna and dna-rna hybridization , mrna isolation-translation , in vitro 2d gel analysis of the translation products , and ultimately the cloning by recombinant dna technologies of genomic dna and copy dnas ( cdnas ) made to poly ( a ) + mrnas , we and others have provided direct evidence for the influence of auxin on the expression of a few genes ( i.e . poly ( a ) + rna levels ) .
