The TTR gene provides instructions for producing a protein called transthyretin. This protein transports vitamin A (retinol) and a hormone called thyroxine throughout the body. To transport thyroxine, four transthyretin proteins must be attached (bound) to each other to form a four-protein unit (tetramer).
Without the reserve ticket the wait for the ferry was 1.5 hrs, it took us about 20 minutes to get through the screening and board the boat. If you have noon or so tickets you can easily visit both Ellis Island and the Statue of Liberty. They also didn't seem to be real strict on the time, we were 1/2 hour early and they just sent us through.
There is only one way to visit the Statue of Liberty and the Ellis Island Museum and that is by ferries operated by Statue Cruises and there are two locations where you can take the ferry. The vast majority of visitors to New York City will take the ferry from Lower Manhattan (see map below).
