Well if that's your attitude I'll post no more on this site.

My definition of tissue and DNA is perfectly all right. The answer to my question is: Scientists have no idea what 98% of the Human Genome is for. They think that 20% is definitely junk, "pseudogenes" and most of the rest has no discernible purpose. But my guess is the bulk of the Human genome does have a purpose and their ignorance of its function merely reflects their general ignorance of the workings of the Human organism, particularly the brain and nervous system. What a shame it is they just can't say "We don't know" instead of "it's all a load of rubbish, there's nothing to know". So when they use matching DNA sequences to justify the inheritability of psychological traits, they may not be able to link those sequences to physical attributes, but you could ask, is that Junk DNA or what is it?

There is no doubt that the DNA Code is responsible for constructing body tissue in all it's manifestations. How else is body tissue constructed? DNA is the blueprint for the construction of the Human body is it not? It's a glorified recipe book for body tissue and nothing more. Have scientists reached the stage where they can take any section of the DNA code and say definitely what type of body tissue that section codes for, or are they still largely ignorant of what much of the DNA code is for? Because they cannot say that a particular sequence is responsible for intelligence, for instance, if they cannot say what physical attribute it is also responsible for.

Hi to all here. Just lately I have taken to correcting people on their use of the word "Gene". "DNA code you mean, a section/sequence of the DNA code" I tell them that DNA codes for body tissue only, therefore when someone says we have found the gay gene, an alcoholic or antisocial gene etc; we have a right to ask for what particular body tissue that DNA sequence codes for. Do scientists actually understand the DNA code well enough to be able to say exactly: that bit's for hair, that for bone and so?
