Using the original DNA sequence in Table 11-4, change the first “G” in code word

Question

Using the original DNA sequence in Table 11-4, change the first “G” in code word 2 to a “T” and rewrite the DNA sequence.

B. The Effects of Base Substitutions, Additions, and Deletions.

Using the DNA sequence in Table 11-4, modify code word 3 by adding a “C” before the first letter “A.” The new chains will be continuous like the original, so don't leave any blanks; write three bases in each box, just as you did for the original.
