Triple Helix DNA

Have you ever wondered what life on Earth would be like if the inhabitants had triple helix DNA?
I'm sure it'd be a lot better than what it is today, considering DNA is the identity of a person.
So if that extra strand of DNA bonded with our existing DNA, what exactly do you think we'd gain?
I think we'd gain a greater understanding of who we are and why we're here.

Who knows, maybe some of the defections in our DNA are just incomplete, and are in need of that other strand to be complete.
There's a bunch of things that could happen.

The problem with triple helix DNA is that it doesn't fit any of the current models. Also, having one more strand wouldn't essentially make organisms better, just more complicated. I don't think we would really gain anything, seeing as regular DNA is double stranded with each strand being the exact opposite of the other. Adding another opposite would make it identical to the first strand, however, it could be helpful for genetic mutations, as two strands would have to be damaged, not just one.

Much of life as we know it is based on double-stranded DNA. The pair of strands is fundamental to how cells reproduce and check for errors in DNA replication. Many proteins function based on a double-stranded model. Therefore, I don't think there is any advantage in having an added DNA strand.
Not only would it not guarantee gained function, it would introduce more room for error and mutation.

In addition, more DNA does not necessarily mean an organism is more complex. Humans do NOT have the largest known genome. That title is currently held by a species of fish.

Triple helix would make WAY more variety, not necesarily more improvement.

Retarded people have an extra cromosome, and... Well...
