That's the basis of inheritance, and science is in the process of analyzing
what each gene does. However, this doesn't explain the process of
Stem cells are those magical units that will develop into anything. (You
recall that they're another political hot potato for this next election,
right?) This means that they're placed into a damaged brain and they become
brain cells to replace those that are missing. If they're placed in a
damaged spinal chord, then they become spinal chord cells.
So what directs this process? How does the DNA know where it's been placed?
There has to be some master program in the body that knows what's damaged
and what's missing, and it has to have a feedback mechanism that keeps track
of progress in fixing things. Since this works in a zygote, which begins as
a single cell, it has to be something within a cell. Nucleus,
mitachondria, cholorplasts, rhibosomes? There's not much choice there. But
possibly each organism has it's own unique electrical field that provides a
It's just another theory, totally unproved at this point.
