Explain this paragraph.
Dear student Please find below the solution of your asked query... The first statement explains that when a single stranded DNA or RNA is tagged with a radioactive probe is allowed to hybridize with its complementary single stranded molecule with no mutation in the gene will easily hybridise because they are complementary to each other, due to the presence of radioactive probe which is attached to the gene will be detected in autoradiography. In the second statement when single stranded DNA or RNA is tagged with a radioactive probe will not hybridise with its complementary gene because they are mutated and after mutation the sequence of gene changes explains the change in Nitrogenous bases due to mutation hence it will not hybridise. Autoradiography detects radioactive probe tagged in the gene and in the second statement as there is no complementary base pairing due to mutation hence it do not hybridise and is not detected in autoradiography. Hope the above mentioned explanation clears your doubts about the topic keep asking Regards
