Question

Which of the following statements is correct for molecular probes?

• A. Used to detect the complementary sequence in nucleic acid samples
• B. Used to introduce recombinant DNA into an animal cell
• C. Used to cut DNA at random positions
• D. Facilitate the multiplication of DNA

Answer 1

The correct option is A Used to detect the complementary sequence in nucleic acid samples

Molecular probes are small DNA or RNA segments that are used to detect the presence of complementary sequences in nucleic acid samples. These segments or probes are labelled either with radioactive or with non-radioactive compound.
