I believe it would be polyphyletic.
Polyphyletic groups are formed when two lineages convergently evolve similar character states. Organisms classified into the same polyphyletic group share phenetic homoplasies as opposed to homologies. The key difference between paraphyletic and polyphyletic groups is that paraphyletic contain their common ancestor, whereas polyphyletic groups do not.
Transcription is important to genetic information. If there is an error during the transcription process, the DNA copies would not be accurate, causing the proteins to be improperly assembled, or not assembled at all.
I believe those are both non-contact forces bc it's not something physical
