T4 uses host nucleotides to replicate its DNA and host ribosomes, enzymes and amino acids to synthesize its enzymes and proteins. During this time no complete phages are found in the host and is called the eclipse period. Tails fibers join the complex. E. coli s plasma membrane and cell wall. The E. coli cell dies.
Burst time is the time from attachment of a virus to lyses and release of the new phage particles.
Burst time ranges from 20 to 40 minutes. Burst size is the number of viruses released from the cell at the burst time. Burst size ranges from 50 to 200 viruses. Some viruses, like phage lambda, can enter a lytic cycle or alternatively, may enter a lysogenic cycle. Phages that can multiply by either cycle are lysogenic or temperate phages.
