A sequential expression of a set of human genes occurs when a steroid molecule binds to the:
messenger RNA
DNA sequence
ribosome
transfer RNA.
Solution
A sequential expression of a set of human genes is the DNA sequence because geneis the functional part of DNA sequence. The steroid hormone receptor-protein complex activates the transcription of the target gene by binding to a specific DNA sequence.
Related Theory
Steroid hormones interact with intracellular receptors and regulate gene expression and protein synthesis. It results in physiological and development effects. The hormonereceptor complex interacts with the genome driving subsequent $m R N A$ and protein synthesis, which brings about tissue growth and differentiation. (Ref. to Fig. 25.3)
