'Is' and 'ought'

[ontological_realist]

" The fact that a living entity is, determines what it ought to do. So much for the issue of the relation between 'is' and 'ought'. "

Could someone please tell me if this is an exactly worded quote from Ayn Rand or some words are being confused? Also where exactly is this written in her writtings?

To summarize the linked post, yes, it is an exact quote.

Context:

In answer to those philosophers who claim that no relation can be established between ultimate ends or values and the facts of reality, let me stress that the fact that living entities exist and function necessitates the existence of values and of an ultimate value which for any given living entity is its own life. Thus the validation of value judgments is to be achieved by reference to the facts of reality. The fact that a living entity is, determines what it ought to do. So much for the issue of the relation between “is” and “ought.”
