Nucleic acid hybridization Nucleic acid hybridization In molecular biology, hybridization (or hybridisation) is a phenomenon in which single-stranded deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) molecules anneal to complementary DNA or RNA. Though a double-stranded DNA sequence is generally stable under physiological conditions, changing these conditions in the laboratory (generally by raising the surrounding temperature) will cause the molecules to separate into single strands. These strands are complementary to each other but may also be complementary to other sequences present in their surroundings. Lowering the surrounding temperature allows the single-stranded molecules to anneal or “hybridize” to each other. DNA replication and transcription of
2-Iodobenzoic acid 2-Iodobenzoic acid 2-Iodobenzoic acid, or "o"-iodobenzoic acid, is an organic compound with the formula ICHCOOH. The synthesis of 2-iodobenzoic acid "via" the diazotization of anthranilic acid is commonly performed in university organic chemistry labs. One of its most common uses is as a precursor for the preparation of IBX and Dess–Martin periodinane, both used as mild oxidants. 2-Iodobenzoic acid can be synthesized "via" a Sandmeyer reaction consisting of the diazotization of anthranilic acid followed by a diazo replacement. First anthranilic acid is treated with nitrous acid in order to convert the amino group into the diazo group. The diazo group
