The answer is the first one: hormone response elements in DNA.

Explanation for each option:

  1. Hormone response elements in DNA: This is correct. Steroid hormones pass through the cell membrane and bind to specific intracellular receptors. The hormone-receptor complex then translocates to the nucleus, where it binds to specific DNA sequences known as hormone response elements (HREs). This binding regulates the transcription of target genes.

  2. Hormone response elements in mRNA: This is incorrect. Hormone response elements are specific DNA sequences, not mRNA sequences. The hormone-receptor complex interacts with DNA to influence gene expression.

  3. Hormone response elements on proteins: This is incorrect. Hormone response elements are not found on proteins. They are specific sequences in the DNA that the hormone-receptor complex binds to in order to regulate gene transcription.

  4. Ribosomes to stimulate translation: This is incorrect. The hormone-receptor complex does not bind to ribosomes. Instead, it binds to DNA to regulate transcription. Ribosomes are involved in the translation of mRNA into proteins, which is a different process.

  5. The cell membrane, thereby increasing its permeability: This is incorrect. Steroid hormones typically pass through the cell membrane due to their lipophilic nature and do not bind to the cell membrane to increase its permeability. The primary action of the hormone-receptor complex is within the cell, particularly in the nucleus where it binds to DNA.

Summary: The steroid hormone-receptor complex binds to hormone response elements in DNA to regulate gene transcription.
