Jack Gilbert explains that studying DNA strands is more effective than trying to identify microbes. One reason for this is
A) most criminals rarely leave a trace of evidence at a crime scene.
B) scientists usually have more time and money for DNA research.
C) most microbes are too large to collect with a cotton swab.
D) microbes are so tiny they can look identical under a microscope.
The correct answer is D) microbes are so tiny they can look identical under a microscope.
Explanation: Studying DNA strands is often more reliable than trying to identify microbes because many microbes are microscopic and can appear very similar to one another when viewed under a microscope. This makes it difficult to distinguish between different types of microbes based solely on their appearance. DNA analysis allows for a more precise identification because it examines the genetic material, which can provide unique signatures for different species.
