5 Must Know Facts For Your Next Test
Burst size varies significantly between different types of viruses.
A higher burst size indicates more efficient viral replication.
Burst size is determined experimentally through one-step growth curves.
Lytic phages typically have larger burst sizes compared to lysogenic phages.
Burst size can be influenced by factors such as host cell type and environmental conditions.
