An investigator wants to study the function of eukaryotic hormone receptors. she has identified the hormone receptors for estrogens and progesterone. she finds that each has a hormone-binding domain, a transcriptional activation domain, and a dna-binding domain. in a cell culture line, she first eliminates the genes for the endogenous estrogen and progesterone hormone receptors. she then introduces a chimeric receptor that contains the progesterone-binding domain fused to the transcriptional activation domain, and dna-binding domain from the estrogen receptor. indicate below whether estrogen and/or progesterone genes are transcribed (induced or not induced) under the given conditions.
