Question

what is probe in Molecular Biology?​

Answer 1

Answer:

Explanation:

probe. Defined nucleic acid (DNA or RNA) that can be used to identify, usually through autoradiography, specific DNA or RNA molecules bearing the complementary sequence

Answer 2

$\huge{\underline{\sf{\red{Answer-}}}}$

Molecular probes are small DNA or RNA segments that are used to detect the presence of complementary sequence in nucleic acid samples. these are usually formed of 200-500 nucleotide sequences. These segment or probes are labelled either with radioactive or with non radioactive compound. Single strandes DNA probes, denatured double stranded DNA probes and RNA probes are used for identification and isolation of DNA and RNA. it is used to probe a sample for the presence of specific protein.
