Gene and Chromosome Location
Date: October 2008
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?
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.
