Unformatted text preview: MULTIPLICATION OF BACTERIOPHAGES After this, biosynthesis of other viral proteins begins. mRNA is transcribed from phage DNA so that any additional phage enzymes and capsid proteins can be synthesized. These are called late proteins. There is a period during which no complete phage particles are present---only the phage DNA and components of the capsid, not yet assembled. This is called the eclipse period. d. Maturation---bacteriophage parts are assembled into complete virions. This assembly occurs spontaneously, without requiring any special enzymes or proteins to do the job. The phage heads and tails are assembled, the head is filled with phage DNA, and attached to the tail. e. Release---this stage is also called lysis. The newly assembled virions are released as the plasma membrane breaks open, due to the action of phage lysozyme which has been synthesized...
