We still don't know, but this review on an ID website gives a reliable and fascinating insight as to how complicated it is. The discussion proposes that DNA doesnot carry all the instructions and describes someof the other known mechanisms, which so far are just a few.

They make a similar argument to Dawkins here that the DNA is a deterministic unit--utterly wrong. Though I know very little about embryonic development, once a cell lives and is manufacturing proteins, you get a very dynamic environment. DNA serves only as "read-only" memory in cells, anything that comes after this is quite clearly the product of various interactions of proteins and cell-stimuli.
