A sequential expression of a set of human genes occurs when a steroid molecule binds to the:

  1. A
    transfer RNA
  2. B
    messenger RNA
  3. C
    DNA sequence
  4. D
    ribosome

Solution & Step-by-step Explanation

Steroid hormones are lipid-soluble and cross the cell membrane easily. They bind to intracellular receptors. The hormone-receptor complex then enters the nucleus and binds to specific DNA sequences (Hormone Response Elements), acting as transcription factors to regulate gene expression.
