What Temperature to Cook a Turkey at?

What temperature to cook a turkey breast at?
I'm not too handy in the kitchen & have no idea where to start. I don't want to burn and ruin my turkey.
What should the temperature of the turkey read when it's done cooking? I want it to be pretty juicy. I'm relatively new to this and any additional information would be appreciated.
How long do i cook a turkey breast and at what temperature in an electric oven?

The best temperature is 375 degrees and about 20-25 minutes for every pound of meat. Get one of those pop-up thermometers, that pop up when it's done, or with a regular meat thermometer it should read 175-180 degrees.
The best tip: no matter how you cook turkey don't overcook it. Don't cook with a clock, cook with a thermometer.
The slower you cook it the more the juices marinated and seep into the meat.

Cooking overnight in a "slow" oven is not recommended for stuffed or unstuffed turkey, since foodborne bacteria can form under these conditions.
