Hybridization is the process of establishing a non-covalent, sequence-specific interaction between two or more complementary strands of nucleic acids into a single complex, which in the case of two strands is referred to as a duplex. Oligonucleotides, DNA, or RNA will bind to their complement under normal conditions, so two perfectly complementary strands will bind to each other readily. In order to reduce the diversity and obtain the most energetically preferred complexes, a techniqu… WebApr 14, 2024 · The temperature does not reach the melting point of aluminum; therefore, only aluminum-rich phases such as Fe 2 Al 5 and Fe 4 Al 13 are formed in solid-state welding processes .
