Final answer:
To mutate the highlighted G to a C, one would change the guanine (G) base to a cytosine (C) in the given DNA sequence. This type of mutation is called a point mutation.
Step-by-step explanation:
If you want to mutate the highlighted G to a C in the given DNA sequence, you would change one base from guanine (G) to cytosine (C). DNA mutations can occur naturally or be induced and can have various effects on an organism depending on the function of the mutated gene. In a laboratory, mutagenesis is the deliberate alteration of a gene, and the simplest form is the point mutation, where a single base pair is changed.
The original sequence is TgtaaagttttctagggttccgcatGtcaattgacatggactgtccgagagaaaacacatacgcgtaa, and the sequence after the mutation would be TgtaaagttttctagggttccgcatCtcaattgacatggactgtccgagagaaaacacatacgcgtaa.
