Question 1 of 5
A segment of DNA that reads the same from forward and backward is called_____.
Correct Answer: B
Rationale: The correct answer is B: Palindromic DNA. Palindromic DNA refers to a segment of DNA that reads the same from both directions. This property occurs when the nucleotide sequence on one strand of DNA is the reverse complement of the nucleotide sequence on the other strand. This symmetry allows the DNA sequence to be read the same forward and backward. Incorrect choices: A: Complementary DNA - Complementary DNA refers to a synthesized DNA strand that is complementary to a given DNA sequence. C: Copy DNA - Copy DNA is not a commonly used term in molecular biology. D: Transcribed DNA - Transcribed DNA refers to DNA that has been converted into RNA through the process of transcription, not DNA that reads the same forward and backward.

Question 5 of 5
An HIV-positive patient who has been started on antiretroviral therapy (ART) is seen in the clinic for follow-up. Which test will be most helpful in determining the response to therapy?
Correct Answer: D
Rationale: Viral load testing measures the amount of HIV RNA in the blood and is the most direct way to assess the effectiveness of antiretroviral therapy. A decrease in viral load indicates that the therapy is working. The other tests provide useful information but are not as directly related to the effectiveness of ART.
