What term describes the rearrangement of DNA sequences by exchanging segments from different DNA molecules?

• A. DNA Recombination
• B. DNA Translation
• C. DNA Replication
• D. Mutation

Answer: (A)

Recombination is the rearrangement of DNA sequences by exchanging segments between different DNA molecules. This shuffling creates new combinations of genetic material and underlies processes like crossing-over during meiosis and various genetic engineering techniques where pieces from different DNA sources are joined. DNA translation is the process of decoding mRNA into a protein, not rearranging DNA. DNA replication is the copying of the genome prior to cell division. Mutation refers to a change in the DNA sequence itself, not the exchange of segments between molecules. Because recombination specifically describes exchanging DNA segments between molecules, it best fits the scenario.
