摘要
Provided herein is a DNA analysis method comprising partitioning a sample into at least a first subsample and a second subsample, wherein the first subsample comprises DNA (e.g., cell-free DNA) with a cytosine modification in a greater proportion; the first subsample undergoes a procedure that affects a first nucleobase in the DNA differently from a second nucleobase in the DNA of the first subsample; and DNA is sequenced to distinguish the first nucleobase from the second nucleobase. Also provided is a combination comprising first and second populations of captured DNA, wherein the first population comprises or was derived from DNA with a cytosine modification in a greater proportion than the second population, and wherein the first population comprises a form of a first nucleobase originally present in the DNA with altered base pairing specificity and a second nucleobase without altered base pairing specificity.
