Hello everyone.
00:01
The given question consists of two parts.
00:03
For the first part we have to draw and explain the structure of bacteriophage polyparch so first of all the capsid head and it is joined to the neck or collar so this is the capsid head and it is ecosahedral it contains phage dna in addition to the this is the second component, it is neck and collar followed by the body sheet.
01:31
And this body, it is actually a sheet surrounding tubular core.
01:46
Further, there are tail fibers which are used to attach to a cell and this is the base plate.
02:01
So this is the structure of a bacteriophage, colipage, t -4.
02:09
In the second part, we have to draw and explain lytic life cycle.
02:22
So first of all, starting with a normal cell.
02:32
Suppose this is one of the normal cells which is attacked by a bacteriophage.
02:47
So the first step is penetration.
02:50
That is the entrance of the viral chromosome.
03:05
So first of all this viral chromosome, it enters the normal cell.
03:16
This is followed by the replication of viral dna...
