<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>
