DNA probe

Abstract

Due to the essentials of modern science in various fields, especially in medicine, DNA technology, there is an increased scope for the identification of various tools. DNA probes are stretches of single-stranded DNA used to detect the presence of complementary nucleic acid sequences (target sequences) by hybridization. DNA probes are usually labeled, for example, with radioisotopes, epitopes, biotin, or fluorophores to enable their detection. DNA probe is prepared for commercial purposes and is believed to be the most sophisticated and sensitive means to identify genes or specific DNA sequences. It serves various purposes in different fields of which its use is incredibly essential. The need for various tools is indeed in medical science. It helps to identify specific DNA sequences and genes.
