One strand of a DNA double helix has the base sequence AGCTTAGGCTA. During replication, a point mutation occurs at the 7th base, changing it from G to T. a. Create the complementary base sequence for the opposite strand of the mutated DNA double helix. (2 marks) b. Identify the specific point mutation that has occurred. (1 mark)
