The mechanism of RNA chain initiation, process is analogous to other biological processes in which DNA unwinding occurs, such as the initiation of DNA replication and site specific recombination. In these latter processes the unwinding or melting of the duplex is often preceded by the tight wrapping of the DNA on the surface of a large protein complex.作者: Fantasy 時間: 2025-3-23 00:31
