Once bound, the 4 translocates into the nucleus. The complex will attach to a specific gene along the DNA. Binding causes the 5 of mRNA for a protein, vitellogenin. Your Answer: 1. hydrophobic 2. plasma membrane 3. cytosol 4. receptor horomone complex nanswered . Question 26 5 / 5 pts Identify the organs or glands numbered in the figure below.
