What is the difference between a non-mutated gene and a mutated gene?



Adenine pairs with guanine or cytosine; guanine pairs with adenine or thymine.


The sequence of DNA bases is different.


The sequence of DNA bases has been removed.


Non-mutated genes express traits; mutated genes remove traits.



Respuesta :

I believe the answer is B. When a DNA sequence changes, it is mutated
Your answer should probably be the option; The sequence of DNA bases is different. This makes sense because the DNA in a mutated gene is different than the usual normal one.

For example, the normal nucleotide sequence for a strand of DNA would be, 

A-C-T-G-G-A-T.

if you add a mutation such as insertion for example ( A-C-T-G-C-G-A-T) it's obviously different now.

Hope this explanation makes sense.
