Repeating sentence in 2 essays?

<p>In short, is it acceptable to copy a sentence from the common app essay to one of the short answers on a uni's supplement? The sentence is also quite unique (finance-specific actually), so i bet anyone would spot it within an hour of reading the two, even if another hundred essays were read in between :)
And if it is bad (which i am sure it is), how bad it is? A no-no?
Thanks for help.</p>
