What is the first stage of the Lytic cycle?
A
Attachment
B
Entry
C
Replication
D
Assembly
Explanation: 

Detailed explanation-1: -The following are the steps of the lytic cycle: Attachment: The attachment of the phage takes place to the host cell surface to administer the DNA within the cell. Penetration: The DNA is injected by the phage into the host cell by penetrating the membrane of the cell.

Detailed explanation-2: -The lytic cycle, which is also commonly referred to as the “reproductive cycle” of the bacteriophage, is a six-stage cycle. The six stages are: attachment, penetration, transcription, biosynthesis, maturation, and lysis.

Detailed explanation-3: -There are five stages in the bacteriophage lytic cycle (see Figure 1). Attachment is the first stage in the infection process in which the phage interacts with specific bacterial surface receptors (e.g., lipopolysaccharides and OmpC protein on host surfaces).

Detailed explanation-4: -1) Attachment: In this step, the bacteriophage, attaches itself by it’s tail to the. 2) Digestion: In this step, the bacteriophage contains an enzyme called. 3) Injection: 4) Taking Control: 5) Multiplication: 6) Rupturing: 10-Feb-2018
