Most steroid hormone receptors are transcription _______ proteins. The receptor steroid complexes bind to the _________ sequences located in 5’-upstream regions of the target genes, to up-regulate the gene activities.
Select one:
a. activator;;;;;;promoter
b. repressor;;;;;;promoter
c. activator;;;;;;enhancer
d. repressor;;;;;;enhancer
e. None of these
Homework Answers
The correct option is a. Activator promoter
Steroidal hormones bind to the receptors and activate the genes by inducing ligand specific conformation of the receptor. This complex bind to promoter sequence and upregulate the gene expression.

1. trans-acting factors are able to regulate target genes from any chromosome, whereas cis-acting elements can only regulate genes located in the same chromosome. a. True only in operons. In Eukaryotic systems, trans-acting factors only regulate genes in the same chromosome. b. True only in Eukaryotes. Prokaryotes don’t have cis-acting elements. c. True for any organism. d. False. The statement is erroneous 2. Unlike activators, repressors never affect chromatin structure. Repressors inhibit transcription only by binding to the binding sites...

Yet, all the cells in your body contain the same
genes (and same alleles). The difference across cell types
is that genes get selectively expressed (turned on or off)
based on the proteins needed for cellular function given their
environment.
