Question

Probes used for detecting genetic sequences are frequently composed of _____

A) synthetic nucleic acids and labeled conjugates, such as fluorescent dyes.
B) nitrocellulose.
C) agarose.
D) silicon chips.
E) restriction enzymes.

Answer 1

Probes used for detecting genetic sequences are frequently composed of a) synthetic nucleic acids and labeled conjugates, such as fluorescent dyes. These probes are linked to a radioactive substance, fluorescent compound, or an enzyme that gives a colored product to aid detection. When a sample of nucleic acid contains a base sequence complementary to that of the probe, the probe binds and allows for the identification of the gene of interest.

Step-by-step explanation:

Probes used for detecting genetic sequences are frequently composed of synthetic nucleic acids and labeled conjugates, such as fluorescent dyes. These probes, also known as nucleic acid probes, are linked to a radioactive substance, fluorescent compound, or an enzyme that gives a colored product to aid detection. When a sample of nucleic acid contains a base sequence complementary to that of the probe, the probe binds and allows for the identification of the gene of interest.
