Are Nikon 50mm 1.8G & 35mm 1.8G weather sealed?

I'm using a D7000 and are finding weather sealed lenses for it. I'm going for a summer trip and knowing they can tolerate some rain is comforting (although I will cover them with ziplock bags if it rains heavily). Do you know any weather sealed Nikon lenses?

They are weather resistant, not weather sealed.

That just means that a few drops of rain won't kill them, but they can't stand a soaking. Neither can the D7000, by the way. While it offers quite some resistance to water drops, i would be reluctant to put that to the test. Water damage is not covered by warranty even in case of cameras/lenses that are said to be weather resistant.
