Ohh, I get it! You see on this diagram where the arrow points to 'hinge region'? Just draw a lines thru the solid bonds nest to the dotted hinge region. The molecule is now broken down to three fragments, and there are still two variable regions where the antigen can bind. I know my explanation's childish, but I hope it helps

For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
