Determine the effect of the following mutations on the DNA sequence. In each case, the mutation is described after the sequence (REFER TO THE SUPPLEMENTAL DOCUMENT FOR GUIDANCE TO THIS QUESTION).
Guanine nucleotide (G shown in red below) was deleted from the DNA sequence at the position indicated by the arrow). Write out the sequence of the mutated DNA and the protein made from it. What is the effect of this mutation on the protein? (For example, how will the mutation affect the length and sequence of the protein? What about the function of the protein?)
