An estrogen-receptor complex within a cell will most likely:
A) be carried through the blood in search of a target organ B) result in the production of an intracellular secondary messenger C) create mutations within estrogen regulated elements of the genome D) bind to DNA, resulting in changes in transcriptional rates

When I did this passage, my guess was choice A. I understand why the given answer is correct, but I still don't understand why choice A would be incorrect, or as the explanation put it "non-sensible." I've looked online and it explains that hormones travel in the blood, in search for a target. Can anyone clarify?

Does the original question say "An estrogen-receptor complex within a cell," like you wrote? If so, you weren't far off at all! Hormones certainly do travel through the blood from the organ of their release to a target organ. The only thing that made A was wrong was the wording of the question - if it's already in the cell, it can't be carried further through the blood - it's already been transported to a target cell and diffused inside.

Lol okay, silly mistake on my part. Thanks!
