Suppose that a casework DNA sample provides only ¼ nanogram of DNA. Which of the following is a strategy that a DNA analyst can use on such a sample?

A) Amplify the DNA with PCR to increase the quantity for analysis.
B) Discard the sample as it is too small for analysis.
C) Use the DNA directly for sequencing without amplification.
D) Send the sample for mitochondrial DNA (mtDNA) analysis instead.
