Finished wine? Wine that you buy in the bottle from a store?
No - with some qualifications.
Yeast is used to make wine -- it is what converts the sugar to alcohol. In a totally dry wine the yeast has died because all the sugar has gone. In a sweet wine fermentation has been halted -- either by adding brandy or by removing the yeast.
There shouldn't be any yeast remaining in finished wine because if there is the wine will start fermenting again. Also the wine will be cloudy. This sometimes rarely happens if there has been a mistake at the winery/
If you buy a wine that has not been filtered or fined (usually a small production wine and noted on the back label as this is something wine lovers appreciate) there is the possibility that some dead yeast cells may be in the wine.
If you buy a well known brand name then no, it is certain that all yeast dead or alive has been removed.

Yes if it has been minimally processed. Possibly no if it is a very large, mass-market wine that has been filtered to sterility to avoid any chance of a "whoops" on the supermarket shelf.
The yeast will work in the juice until it has consumed all the sugar (gone "dry") or until it creates so much alcohol that it kills itself off (around 16%). Most wines go dry before this point however, so they do contain active (but dormant) yeast.
If you want to know, take a small amount of wine and add it to a cup of sugar solution and see if fermentation takes off in a few days. (Bubbles, foam, etc)

yes.
being a maker of wine yeast is very important that's the part that makes the alcohol... the yeast cultured, thrown into the concentrate or whatever elements you are using as the major fruits of the batch and when the yeast ferments into the culture well you get alcohol!
of course how it ferments depends on the gravity of the alcohol... most wines have 11% alcohol content per liter.

Yeast is used in making the wine, but there is no yeast in the finished product.

Yes. All wines are made by yeast converting sugar to ethanol. It's fermented.

yeast is used in the winemaking process. It is removed at various stages depending on how they want the wine to taste.
