A frameshift mutation is a type of mutation involving the insertion or deletion of a nucleotide in which the number of deleted base pairs is not divisible by three. "Divisible by three" is important because the cell reads a gene in groups of three bases. Each group of three bases corresponds to one of 20 different amino acids used to build a protein. If a mutation disrupts this reading frame, then the entire DNA sequence following the mutation will be read incorrectly.

B. In the second instance, the proteins will contain the radioactivity this is because, the DNA does not have any reaction with sulphur, on the other hand, proteins contain about 3 - 6% sulphur.
