A sequence of DNA, AAAATGCTTCTC, codes for a specific order of amino acids. Through the processes of transcription
and translation, the code in the DNA is converted to a protein. According to the model, which DNA change would have
the greatest change to the phenotype of an organism?
-)
A)
The substitution mutation has the greatest impact because it occurs in the
middle of the amino acid chain.
B)
The insertion mutation has the greatest impact because the additional
cytosine nucleotide changes the DNA's orientation
None of the DNA changes will have a change to the organism's phenotype
since the mutations still result in functional protein assembly
The deletion of a nucleotide near the beginning of the sequence has the
greatest impact because it alters all of the amino acids after the nucleotide
removal
D)
