The number of phage particles present on this plate is 50 Million phages.
When a plague started with one phage, after 1st round of replication it will produce 10 virus particles. After another round, each of the 10 viruses will produce 10 virus particles each, totaling 100 particles. And then after 3rd round, each of the 100 phages will produce 10 each = 1000 phages. So, (10)^3
Initially, 400 phages are present, and the burst size is 50., After 3 rounds, the number of phages will be = 400× (50)^3
= 50 Million phages.
DNA replication is the procedure via which a double-stranded DNA molecule is copied to provide identical DNA molecules. Replication is an essential method because, each time a mobile divides, the two new daughter cells must comprise the same genetic information, or DNA, as the discern cell.
