Indeed the ultimate problem in biology and I think the biological 'holy
grail' is the problem of predicting phenotype from genotype. This means,
as you state above, to predict physiology from proteins, proteins from
the amino acid sequence and amino acid sequence from DNA sequence. I am
convinced that many molecular biologists feel the these problems are
solved and certainly understanding metabolism (or anything for that
matter that happens down stream of the proteins) is solved - I mean just
check out the many text books on biochem! The pretty pictures and rosy
impression depicted in modern text books however hides an enormous gulf
between image and understanding. I am not denigrating mol biol or
related disciplines when I say that the problems and questions
considered in mol biol pale in to insignificance compared to cellular
dynamics. Likewise the problems we encounter in cellualr dynamics pale
yet again into insignificance when compared to the problem of the brain.
Is the surface even scratched, perhaps the paint work is slightly pale?
