These viruses are strands of RNA that attach themselves to other RNA strands, including those that come from dividing DNA molucules. The trick is to create binding points on the avian flu or swine flu virus that will link up to complimentary points on the human influenza virus. Then though recombinations of these strands, come up with a hybrid that is as easily tramsmitted as the human flu but has the damaging characteristics of thw swine flu.
Thanks. It’s been a while since I’ve studied some of this stuff. I’m remembering more since reading your post, and understanding better as well. Thank you so much! :)
