The DNA probe used in DNA fingerprinting consists of ____(A)____ and labeled with ____(B)____.
Choose the correct options for (A) and (B) respectively.
Options:
Answer:
D
Solution:
A DNA probe is a small, known sequence of single-stranded DNA or RNA that is complementary to the specific sequence of DNA being sought.
It is labeled with a radioactive isotope (or a fluorescent tag) so that it can be easily detected after it hybridizes with its complementary target sequence on the nitrocellulose membrane during DNA fingerprinting.
Therefore, (A) is a known sequence of single-stranded DNA and (B) is radioactive isotopes.
Answer: (A) known sequence of single-stranded DNA (B) radioactive isotopes
