Taxes on life insurance proceeds and giving those proceeds to a relative

To whom it may concern,

Recently my wife passed and at the time we weren't on good terms.  She had a life insurance policy that I was the beneficiary, but was supposed to change the beneficiary to our daughter, but didn't do it before her death.  So my question is 2-fold:

1.  Are the proceeds from the insurance policy taxable?

2.  When I give those proceeds to my daughter, will she have to pay taxes?  She currently is not working and planning on attending a PhD program abroad.

 

Thanks
