A mutation in the code for a trait may not always change the expression of that trait. What advantage does this provide cells? Ribosomes can produce proteins more quickly.
Cells only need to make a limited number of proteins.
Proteins can switch tasks without a change in the DNA sequence.
Some changes in the DNA sequence will not cause a change in the protein produced.

Some changes in the DNA sequence will not cause a change in the protein produced.

Explanation:

My reasoning is, if the mutation is not expressed then the changes in the DNA sequence will not affect the coding for whatever protein will be produced. The mutation won't affect anything, it is like the mutation is invisible. I hope it helps plus by process of elimination the others would be wrong.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
