Abstract
The present disclosure provides compositions and methods related to analyzing DNA, such as cell-free DNA. In some embodiments, the cell-free DNA is from a subject having or suspected of having cancer and/or the cell-free DNA includes DNA from cancer cells. In some embodiments, the DNA is partitioned into a first subsample and a second subsample, wherein the first subsample comprises DNA with a nucleotide modification (e.g., a cytosine modification) in a greater proportion than the second subsample, and the second subsample is subjected to a procedure that affects a first nucleobase in the DNA differently from a second nucleobase in the DNA of the first subsample, and the DNA is sequenced in a manner that distinguishes the first nucleobase from the second nucleobase in the DNA of the second subsample.
