Lambda phage which of the following is true ?
Ans. is 'c' i.e., lysogenic form incorporates in host DNA and remain dormant . Lambda phase is nothing else but prototype of bacteriophage. . It has already been explained in previous explaination that lysogenic form is incorporated into the host genome ( not in lytic phase). In lytic phase,there is replication of phage inside the bacteria that causes lysis of bacteria. . On exposure to ultraviolet light or other agents the lysogenic phase undergoes induction i.e., the phase DNA is excised from the host cell and it undergoes lytic cycle.
It causes mad cow disease
Lysogenic to lytic conversion cannnot occur
Lysogenic form incorporates in host DNA & remain dormant
Lytic phase incorporates in host DNA, proliferate & causes rupture of cell
