Please answer the questions below.
9. How do peptide hormones affect a target cell’s transcription?
a. They bind to the receptor on plasma membrane and initiate a signaling pathway that regulates transcriptions.
b. They bind to the plasma membrane get taken inside and bind to the DNA.
c. They enter the cell and bind with a receptor in the cytoplasm then bind to the DNA.
d. They enter the cell and bind with a receptor in the nucleus on the DNA.
10. What sequence describes how a steroid hormone impacts gene expression?
a. Steroid hormone crosses the plasma membrane, binds to an intracellular hormone receptor in the nucleus, then regulates transcription.
b. Steroid hormone binds with a plasma membrane receptor, then crosses the plasma membrane, then binds to DNA and regulates transcription.
c. Steroid hormone crosses the plasma membrane, binds to an intracellular hormone receptor in the cytoplasm, the receptor hormone complex then binds to DNA and regulates transcription.
d. Steroid hormone crosses the plasma membrane, binds DNA and regulates transcription.
