Question

What is a characteristic of nucleic acid probing?

a.) It can use radioactive phosphorus to identify a DNA fragment of interest by autoradiography.

b.)It is used to make numerous copies of a DNA sample.

c.)It is used to compare DNA banding patterns after restriction digestion.

d.)It is used to separate DNA fragments by size.

Answer 1

a.) It can use radioactive phosphorus to identify a DNA fragment of interest by autoradiography.

Step-by-step explanation:

For nucleic acid probing, the probes are often labeled with a radioactive or fluorescent tag, such as radioactive phosphorus, to allow detection. When the probe hybridizes (pairs) with its target sequence, the location of the probe can be detected using autoradiography or other detection methods.
