Question

which of the following determines the specificity of a DNA probe?
A. type of radiation
B. level of enzymatic activity
C. number of neutrons
D. complementary base pairing

Answer 1

Answer:

Complementary base pairing

Explanation:

DNA probes are the single stranded stretches of nucleotides that are complementary to the original strand. DNA probes are used in various molecular technologies like polymerase chain reaction and DNA finger printing.

DNA probes can only hybridize with the specific complementary base pairs. Hence, complementary base pairing determines the specificity of DNA probe.

Thus, the correct answer is option (D).
