WebApr 14, 2024 · It uses its crown of proteins to fuse to a host cell surface or a cellular package called an endosome, which is engulfed by cells. Once inside the host cell, the virus uses the first two-thirds of its genome to replicate. It copies its genome and makes structural proteins critical to form new viruses that will soon escape the host cell. WebThe rate of DNA replication in a living cell was first measured as the rate of phage T4 DNA elongation in phage-infected E. coli. During the period of exponential DNA increase at 37 °C, the rate was 749 nucleotides per second. The mutation rate per base pair per replication during phage T4 DNA synthesis is 1.7 per 10 8.
