<p>On part b of the first question of the 2002 AP exam, the question is:</p>
<p>(b) All humans are nearly identical genetically in coding sequences and have many proteins that are identical in structure and function. Nevertheless, each human has a unique DNA fingerprint. Explain this apparent contradiction.</p>
<p>Can someone provide me with YOUR sample answer?</p>
<p>I’m having a bit of trouble formulating my own answer.</p>
<p>talk about tandem repeats. these are noncoding sequences of DNA that differ in almost all humans. Different individuals have different random sequences of DNA repeated in various locations within their genome. Tandem repeats are especially helpful in forensics to help identify criminals.</p>
<p>Thanks. I forgot about those!</p>
<p>no problem, i didn’t think tandem repeats would be that big a topic to dedicate a whole question to it lol.</p>
<p>Yes tandem repeats are good to talk about and how also relatively few genes contribute to individual differences as the many that contribute to similarites, but that those genes that contribute to individual differences do have an extreme physiological effect.</p>
<p>How did everyone do on the AP Biology Exam?</p>
