Say I have a WT gene transcript, where this particular gene encodes for a particular protein. Now I knock out the expression of the gene so that it can't make the protein (knockout mutant). I do this by making mutations on the gene so that the expression of the protein will not be made.
Now, I am still not 100& sure that that mutation caused the knockout or if I disrupted something else in the mechanism that also caused the knockout. So I want to create a complement line to test if the knockout is really linked to the mutation.
This is where I am stuck: To make a complement line, how exactly do you go about this? Can you just take the wild-type gene sequence of that protein and place it back into the knockout gene transcript? Or can you 'fix' the mutations? And how do you go about doing that?
