The replication fork forms at a specific point called autonomously replicating sequences (ARS). Plasmids are autonomously replicating circular extra-chromosomal DNA. Endogenous antigens are produced by intracellular bacteria and viruses replicating within a host cell. Plasmids are considered "replicons", units of DNA capable of replicating autonomously within a suitable host. MicroRNAs also play a role in replicating viruses such as HIV-1. With respect to viral infections, in incubation the virus is replicating. HDFS uses this method when replicating data for data redundancy across multiple racks. Think about replicating the changes in other processes. They can consume dead creatures, memorizing and replicating the physical traits perfectly. A von Neumann probe is a spacecraft capable of replicating itself. Classic RISC pipelines avoided these hazards by replicating hardware. They are player pianos replicating his physical motions. Solutions include replicating some code, or adding boolean variables. Replicating Burmese sounds in the Latin script is complicated. RepRap is short for replicating" rapid prototyper".
