We actually do know that, proteins which control expression of other genes handle the morphology. There's a gene for a left side, for example.
But the relevant thing is, they control expression by binding to pieces of non-coding DNA, which can be considered "junk" by strict definitions. So most genes are prepended by a block of if-statements.

- thriftwy 4y agoThe patterns of what? Gene expression is an area of active research.
- graderjs 4y agoMorphology. Shape of things. How we get arms etc. We don't know how to engineer genetics to produce desired shapes. In the 'junk' that's where the secret is...not covered by most of the current published research in gene expression...and nothing like traditional gene expression (rna transcription -> protein + signaling). Currently published science basically knows nothing about how to get shape from DNA
