Sister chromosome exchanges are recombination events that occur between homologous chromosomes and are often the result of exposure of the cell to DNA damaging agents. 
Cross over, or recombination, is the exchange of chromosome segments between non sister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.

Mutations in DNA include deletions and insertions. These types of mutations:
pantera1 [17]

Answer:

(A). Result in different amino acids to be read due to frame shifts

Explanation:

Insertion or deletion mutations (or Indel mutations) can be defined as mutations in DNA due to insertion (addition) or deletion of nucleotide bases in DNA.  

These mutations lead to change in reading frames (sequence of codons), which leads to formation of protein having completely different amino acid sequence. Hence, these mutations are also cause frameshift mutations.

This is due due to triplet nature of genetic codes as insertion or deletion of one or more bases (but not three) would change change in codon sequence and mutated sequence can form a non-functional or truncated protein.

Thus, the correct answer is option (A).
