Question

which point made by the speaker supports his statement that dna is an important tool in solving crimes when no fingerprints can be found? he describes the dna structure found in human cells. he explains that everyone has unique dna, making it easy to identify a single person using their dna. he shares the interesting fact that identical twins share the same dna. he details the fact that humans have millions of cells.

Explanation:

The uniqueness of DNA allows for individual identification, which is crucial in crime - solving when fingerprints are unavailable. Describing DNA structure or the number of human cells doesn't directly relate to its use in identification. The fact about identical twins sharing the same DNA doesn't support the use of DNA for individual identification in most cases.

Answer:

He explains that everyone has unique DNA, making it easy to identify a single person using their DNA.
