Okay, so the protein bch can be produced in genetic engineering bacteria.
00:16
But to cut the bch gene out of the cow chromosome so that we can get it into the bacteria, this is done through the use of restriction enzymes to cut the gene of interest.
00:40
Out.
00:42
So that instead of this whole sequence, we just get, we just get this gene.
00:56
Assuming, of course, that this gene is flanked by those restriction enzyme sites.
01:14
That was question one.
01:15
Question two, a cow produces a protein called bovine growth hormone, bgh, and increases the milk production of protein, bch .h, i'm thinking that means that this isn't supposed to be bch but actually bgh.
01:32
So the protein bghh can be produced genetically engineered a bacteria purifide and then injected into cows.
01:43
The dna molecule that includes both the cow and the bacterial gene.
01:49
So let's say this gets put into the bacteria in the form of say a plasmid with this bgh.
02:07
Gene.
02:10
So what is this dna molecule because this is a plasma this whole thing is a dna molecule.
02:16
What is this dna molecule called? this is generally going to be known as a recombinant dna and it's recombinant because we have literally recombined two things, the plasmid and the gene of interest.
02:53
We've at least recombined two things.
02:56
That's why this is called a recombinant...
