Question:
Are completely identical genes found in different positions in the DNA or do they always appear in the same sequential order. For example: If genes a b and c appear in a strand in the order of a, b,c can they also appear as: b, a, c? And if so, does it make a difference?


Replies:
Ordinarily, genes always maintain their sequential order. Genes are regions of a DNA molecule that are faithfully replicated every time the chromosome duplicates. Accidents due occur sometimes causing inversions, duplications, deletions or translocations of genes.
