the claim

All cellular life forms, including bacteria, archaea, fungi, and protists, use DNA as their genetic material.

the verdict
INSUFFICIENT LEANING
Recorded sources
5 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that all cellular life forms, including bacteria, archaea, fungi, and protists, use DNA as their genetic material?

Unclear. Several reference and peer-reviewed sources state or assume that DNA is the genetic material across life forms, including a NASA astrobiology feature on eukaryotes and a Wikipedia article calling DNA the primary genetic material for all known life. None of the placed items directly and fully settles the claim for bacteria, archaea, fungi, and protists together.
