Transduction is the transfer of dna from donor to recipient by a, crossing over, b, a bacteriophage, c, cell to cell contact, d is naked dna, e, bisexual reproduction.
00:14
So we're looking at something called horizontal gene transfer here.
00:19
So horizontal gene transfer is the movement of dna to a member of the same generation.
00:31
So what we mean is it's not from parent to offspring.
00:35
It's not a cell splitting into two daughters.
00:37
It is the actual transfer of dna from one to appear.
00:43
So parent to offspring is vertical.
00:45
This is horizontal.
00:47
And there are three methods we see in bacteria.
00:50
Those are transduction, transformation and conjugation.
00:56
So you need to know what each of these mean.
00:59
So we'll start the answer.
01:01
Transduction is b.
01:03
It's by a bacteriophage...
