Question

Can specified transduction be lysogenic?

Answer 1

Are you asking if lysis plays a role in transduction? Because that would make sense.

Take a look at this picture of transduction:

See Frame #3?
There's lysis.

And well, I don't see how specific transduction should be any different.

Answer 2

I'm not talking about lysis, I'm talking about the lysogenic cycle (not the lytic)

Answer 3

Oh I'm so sorry. I don't know how I misread that.

Hold on.

Answer 4

Your answer seems to be "yes."

Transduction can happen through the lysogenic cycle (as well as lytic).

~~~~~~

This is how I see it: And it's just the basic concept:

The virus injects its genetic material into the bacterium.

The virus's genes combine with the bacterium's genes,
and it enters the lysogenic cycle.

After that, every time the bacterium divides,
the virus's genes will be seen in each of the new bacteria.

I'm looking at this wiki article on transduction:
http://en.wikipedia.org/wiki/Transduction_(genetics)

Second section.
It pretty much tells us that transduction can happen through either lytic or lysogenic cycles,
and it covers the basic idea of lysogenic cycle.

Answer 5

Makes sense.

Answer 6

Mm hm. I mean I don't see any other way that the genes could transfer while the virus is dormant in the lysogenic cycle.

Answer 7

Gene transfer doesn't equate gene expression though. I was overthinking the question.. By entering the lysogenic cycle, the fact that the DNA incorporates itself into the host DNA makes it transduction, right?

Answer 8

Sure, if the virus is carrying genes from another bacterium,
and it has integrated those genes into a new host,
then we have transduction.
