The mutation that causes sickle cell anemia can be tested for by:
1)Testing for the presence or absence of a specific restriction enzyme cleavage site in DNA
2)Testing for the presence of a trinucleotide repeat in DNA
3)Testing for the absence of a trinucleotide repeat in DNA
A) 1
B) 2
C) 3
D) 1 and 2
E) All of these

Question

Quizplus · Accepted Answer

The mutation causing sickle cell anemia results in the loss of a restriction enzyme cleavage site in the DNA, allowing for its detection through restriction enzyme analysis. Trinucleotide repeats are associated with other genetic conditions, not sickle cell anemia.
