analysis of the same samples of rna using a probe derived from the 3 ' terminal intron segment of the rat aromatase cdna clones that lack the heme-binding domain indicates that two of the species of aromatase mrna transcripts present in both rat ovary and r2c cell lack the heme-binding domain and thus must encode a nonfunctional aromatase protein .
