Do DNA and genetics ever lie?

Answer 1

DNA was first used in computing to solve a small version of the directed Hamiltonian path problem, an NP-complete problem.[102] DNA computing is advantageous over electronic computers in power use, space use, and efficiency, due to its ability to compute in a highly parallel fashion (see parallel computing). A number of other problems, including simulation of various abstract machines, the boolean satisfiability problem, and the bounded version of the travelling salesman problem, have since been analysed using DNA computing. Due to its compactness, DNA also has a theoretical role in cryptography, where in particular it allows unbreakable one-time pads to be efficiently constructed and used.

Answer 2

There are chimeras: people with two sets of DNA. This happens when the person was originally a set of fraternal embryos but they fused back together into one person early on in the womb. This leads to chimeras with babies to be mistaken for fakers when DNA testers find that the DNA of the chimera doesn't seem to match the baby's. But this is human error, not the intentional deception of DNA and genetics.

Edit: Whoa, I must have been watching aurora's program!

Answer 3

Yes. I watched this fascinating program about this very subject. A lady was told that she was not the mother of her children because her DNA didn't match the children. It turned out that she had two separate strands of DNA, and the one commonly used in DNA tests was not the one that she had passed on to her children. So, I have to say yes.

Answer 4

DNA and genetics never lie.. BUT..

If you have a identical twin, you can not tell the difference.

Answer 5

Only when there is human or mechanical failure in the test procedures.

Answer 6

It is truth; it can be misinterpreted by human error.

Answer 7

No
