Question

Quizplus · Accepted Answer

Many of the eukaryotic genes involved in information processing, such as those related to transcription and translation, are believed to have originated from an archaeal ancestor. This is supported by genetic and molecular evidence showing similarities between the information processing mechanisms of eukaryotes and archaea.
