It was a copying error. One enzyme cut it up, one didn't move it out of the cell fast enough, another stitched it back together incorrectly.<quoted text>
Could that fusing be the result of gene splicing, or did someone stand too close to the microwave?
How was the bond made? Not the technique, but the molecular linkage? Anything removed to bond them? Which chemicals bonded at the ends?
I don't know the specifics of the molecules involved. It's telomere DNA to non-telomere DNA bonded together. A telomere is just DNA that is repeating in a certain pattern. So it ends up being DNA-DNA bonds, like any other part of the DNA only recognizable as telomere rather than coding or noncoding sequences. That makes it one of G A T C attached to its opposite pair, just like in all DNA.
Sadly, no microwaves at that time, but my chromosomes just fused because of this damned computer.
