Question

QUESTION 28 Acyl homoserine lactones are small molecules involved in which process? catabolite repression O nitrogen assimilation stringent response O quorum sensing QUESTION 29 When a virus enters a host cell in which it can replicate, the process is called a O Prophase Excision Infection Insertion QUESTION 30 The first step in the infection cycle of a virus is O replication of its genome O degradation of the host genome lysis of the host cell O attachment to the host cell surface

Answer 1

28.d.qorum sensing

acyl homoserine lactones(AHL) are signaling molecules involved in bacterial quorum sensing.

29.c.infection

virus infection takes place when virus enters in host body and multipies itself to many copy to surive.

30.d.attachment to the host cell surface

virus first attachs to the surface of host then insert its genome, which is followed by replication of viral genome then it degrades host genome and thus results in lysis of host cell.
