explain the differences bet tween a gene mutation and a chromosome mutation?

Answer 1

A chromosome mutation is a change that involves a part of, or an entire chromosome: examples: non-homologous translocations,
additions or deletions caused by chromosomal breakage and reattachment, inversions, nondisjunction, polyploidy, to name a few .

A gene mutation involves a change in DNA, like mis- pairing of the N-bases .This is considered a biochemical change.

There are specific genetic disorders in humans associated with either chromosome or gene mutations.

Answer 2

Mutation = irreversible change of DNA.

Basically, there are three types, based on the severity of the change:

Change of the number of chromosomes (trisomy, monosomy)
Change of the structure of chromosomes (translocation, deletion)
Gene mutation - where the change is on the nucleotide level.

The first two are chromosome mutations, the third is gene mutation.

Answer 3

ermmm arn't they the same? because genes are what makes up chromosomes.....
