DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. This technology has revolutionized medicine by allowing doctors to identify genetic predispositions for certain diseases. [Proposed sentence: Forensic scientists also use DNA sequencing to identify suspects in criminal investigations by matching evidence found at a crime scene.]
Should the writer add this sentence here?
- No, because it repeats the information about the order of nucleotides that was already mentioned in the first sentence.
- No, because it introduces a detail about criminal investigations that deviates from the paragraph's focus on medical science.
- Yes, because it provides an additional, relevant application of DNA sequencing technology in a field outside of medicine.
- Yes, because it explains the biological process by which DNA is collected and preserved by law enforcement officials.
