PROBLEM:  Members of the steroid / hormone nuclear receptor superfamily regulate target gene transcription via recognition and association with specific cis - acting sequences of DNA , called hormone response elements ( HREs ) .

SOLUTION: nuclear receptor superfamily

PROBLEM:  Reactive mesothelial cells , usually seen as exfoliated cells , were consistently strongly positive for alpha 1 - antichymotrypsin and more variably for alpha 1 - antitrypsin and lysozyme .

SOLUTION: alpha 1

PROBLEM:  These proteins were detected by an antibody which recognizes the N - terminus of SRK3 and , in an F2 progeny segregating for the S3 haplotype , were only expressed in plants possessing the S3 haplotype .

SOLUTION:
S3 haplotype
