It would be C because it didn't change what amino acid it was
Robert Hooke discovered Nucleus in the cell !!
So, C is the most appropriate answer !! as nucleus contains genetic material and is passed to daughter cells !!
Noncoding sections are used in dna fingerprinting, as they are easily identifiable, abundant, and passed on from parent to child through genes. If you can get a relative with similar noncoding sections, then you could compare similarities in the DNA.
I'm not completely sure but I think is the C please tell me if I'm wrong
