Genetic Engineering: Vectors

Post by Mio » Mon Feb 15, 2010 6:58 am

Good day everyone!

I was posted this question recently, and found it difficult to answer with logical reasoning. I did some research on the net but to no avail-

Why must there be two genetic markers per vector molecule used in genetic engineering?

Any help would be greatly appreciated.

With two markers, you can use more combinations with other vectors, you have higher selection pressure, than with only one marker...

What vectors are you reffering to? For what genetic engineering?

Cis or trans? That's what matters.

It depends what you are doing. You don't always need two markers.
