Question

the diagram shows a segment of dna that codes for a genetic disease. which factor most likely affected the dna as shown in the diagram? base pairing mutation parasite bacterial infection

Explanation:

• Base pairing is a normal function in DNA (A - T, C - G). In the given diagram, there seems to be an abnormal pairing (not following the standard rules).
• A mutation is a change in the DNA sequence. The abnormal base - pairing shown in the diagram is indicative of a mutation.
• A parasite is an organism that lives on or in another organism. It does not directly cause such base - pairing irregularities in DNA in the way shown.
• A bacterial infection is caused by bacteria. Bacterial infections do not typically result in the kind of base - pairing anomalies depicted in the DNA segment diagram.

Answer:

mutation
