Question

Eukaryotic gene regulation integrates signals from the environment by all but which of the following?

A) Transcription factor dimerization
B) Ligand-receptor interactions
C) DNA strand separation at the TATA box
D) Protein phosphorylation
E) Endocrine signaling

Answer 1

Eukaryotic gene regulation integrates signals from the environment through various mechanisms such as transcription factor dimerization, ligand-receptor interactions, protein phosphorylation, and endocrine signaling. DNA strand separation at the TATA box, however, does not play a direct role in this integration.

Step-by-step explanation:

Eukaryotic gene regulation integrates signals from the environment through various mechanisms. However, one of the options provided, DNA strand separation at the TATA box, does not play a direct role in integrating signals from the environment. The correct answer is C) DNA strand separation at the TATA box.

Transcription factor dimerization, ligand-receptor interactions, protein phosphorylation, and endocrine signaling are all examples of mechanisms involved in eukaryotic gene regulation. These processes allow cells to respond and adapt to changes in their external environment.
