Mutations can occur randomly during DNA replication. Suppose DNA replication is occurring in a cell. If DNA replication occurs correctly, the following strand will be produced.

Question

If a point mutation occurs during DNA replication, which of these could represent the mutated strand produced instead?
A.

B.

C.

D.

Answer 1

Without the provided options, it is impossible to determine the specific mutated strand that would be produced. The options for the mutated strand could include a substitution mutation (where one base is replaced by another), an insertion mutation (where an extra base is added), or a deletion mutation (where a base is removed). Each of these mutations would result in a different mutated strand.
