<p>So I checked out the sample AP Biology MC questions on College Board's apcentral, and I am wondering if the sample questions they provide are relatively accurate to what the real MC questions are? </p>
<p>Feedback is much appreciated.</p>
<p>Yes, the sample questions are pretty accurate to the actual exam.</p>
<p>Thanks fabrizio.</p>
<p>Sample questions in general in the course description do seem to be slightly more difficult than the average question, though.</p>
<p>Sweet. They seemed easier than I excepted though. :) I was expecting alot more specific questions like enzymes and etc.</p>
<p>I have a couple of questions regarding the subject though:</p>
<p>Where are the phytochromes located?</p>
<p>Is lytic cycle and lysogenic cycle exclusive to prokaryotes or do these cycles exist in eukaryotes, but with slight variations?</p>
<p>Are operons exclusive to prokaryotes? Or do operons also exist in eukaryotes?</p>
<p>phytochromes: on the in thylakoid membranes of chroloplasts.</p>
<p>Lytic and lysogenic cycle: I'm not sure but I think not since how virus gets into its host cells depends on host cell's outside structures. And I don't think this question will be on the AP exam.</p>
<p>Operons: They also exist in eukaryotes. But this won't be on the AP exam. It's too ambiguous.</p>
<p>Thanks valecollegorian. </p>
<p>Phytochromes aren't photosystems right? The two are independent of each other?</p>
