Question

Why is the sequence of DNA important?

Answer 1

Every 3 base pairs codes for a different amino acids. Even though amino acids each have two or three different codes for them. The amino acids then are linked in the order that they appear in a segment of DNA into protiens. The order of amino determines how the protiens folds and twists which determines the overall shape. The shape has to be exactly right or the protien will not function properly.

Deformed protiens can cause lactose intolerence, sickle cell animia, some allergies.
If the deformity occurs in a protien that is crucial like DNA striptase which allows DNA to be replicated, it can cause death.

In about 16% of your DNA the order doesnt matter because it doesn't code for anything. This is so that hopefully at least some of the mutations will occur here and have no effect on the cell.
