Question

Examine the two strands of DNA below. Which kind of mutation occurred? Original strand: AGC GTA CCC TAC New strand: AGC GTA ACC TAC

what is the answer
frameshift
substitution
insertion
deletion

Answer 1

The mutation that occurred in the given example is a substitution mutation. In the original strand, the codon "CCC" is mutated to "ACC" in the new strand. This differs from a frameshift mutation where the insertion or deletion of nucleotides would cause a shift in the reading frame of the DNA sequence.
