Which is even more remarkable considering that all human beings are very nearly identical, genetically-speaking. Regardess of race. But that 0.05 per cent gap is all there is to account for why one person differs from another. And this small genetic variability lies at the heart of a new insight that puts paid to the belief that it is all in the genes. There is more mixing and matching of parts during protein synthesis in humans than was expected.
Human genes are also able to accessorise the proteins they make.
That is, human proteins can dangle little molecules of sugar or phosphate, changing their functions tremendously. Animal genes, on the other hand, cannot do these tricks. In sum, human proteins are put together in much richer sets of complex combinations than previously imagined. So rich in fact they account for the human variation and diversity we see around us. So similar genes can, in a sense, be slightly different too.
