Why can an error in DNA or chromosome(s) result in a variant trait problem?

Answer 1

b/c the amino acid sequence would change and therefore the code would translate to something else

Answer 2

If a single base in DNA is changed, that can cause a different amino acid to be placed into a protein. A number of genetic diseases are cause by such small changes. The reason is that a single amino acid difference in a protein can cause the protein molecule to be unable to carry out its function.

Answer 3

transformations in DNA led to by using mutation could reason blunders in protein series, coming up in part or thoroughly non-useful proteins. to perform properly, each cellular relies upon on hundreds of proteins to perform contained in the suitable places on the suitable circumstances. whilst a mutation alters a protein that performs a serious place contained in the physique, a scientific difficulty can result.
