You're researching a steroid hormone that binds to a receptor inside the cell.Once the receptor binds to its hormone,the receptor moves into the nucleus of the cell.The result of hormone-receptor binding is that new mRNA molecules are made.The receptor is also a
A)ribosome.
B)transcription factor.
C)tRNA molecule.
D)promoter.
E)splicosome.

Question

Quizplus · Accepted Answer

The fact that the hormone-receptor complex induces the production of new mRNA molecules suggests that the receptor acts as a transcription factor, which binds to specific DNA sequences in the nucleus and controls the initiation of transcription by RNA polymerase. Ribosomes are cellular structures that synthesize proteins based on the information encoded in mRNA molecules, and tRNA molecules are responsible for bringing amino acids to the ribosomes during protein synthesis. Promoters are DNA sequences that RNA polymerase binds to in order to initiate transcription, but they are not typically associated with steroid hormone receptors. The spliceosome is a large complex of RNA and protein molecules involved in the processing of pre-mRNA into mature mRNA molecules by removing introns and splicing together exons. However, this process occurs in the nucleus and is not directly related to the hormone-receptor interaction.
