very hard ACT question

<p>I am so confused about a certain ACT question in the official prep book (red book). This is on page 110, question 13:</p>

<p>I think the answer should be A, when the answer in fact is D. My reasoning is that if gene x is replicated first, then gene r and gene s should be replicated next. Thus, gene G would not be replicated after 45 minutes...</p>

<p>where is my logic wrong??
Please help!! thanks</p>

<p>Gene G is the correct answer.</p>

<p>i know, but why does my logic not make sense?? I did not end up getting gene G as the answer</p>

<p>Oh, I thought you were saying Gene G is correct, and the book-answer is different.</p>

<p>Sorry, too lazy to read the passage)</p>

<p>can someone please help me out here? It will also help yourself if you are preparing for ACT</p>

<p>I would if I had the book on me, but I don’t</p>
