By comparing the composition of transcription factor families and regulatory network motifs between unicellular organisms and multicellular organisms, scientists found there are many novel transcription factor families and three novel types of regulatory network motifs in multicellular organisms, and novel family transcription factors are preferentially wired into these novel network motifs which are essential for multicullular development.
Ao compararen a composición de familias de factores de transcrición e motivos de redes regulatorias entre organismos unicelulares e organismos multicelulares, os científicos encontraron que hai moitas familias de factores de transcrición novas e tres novos tipos de motivos de redes regulatorias en organismos multicelulares, e as novas familias de factores de transcrición están preferentemente conectados nestes novos motivos de redes, que son esenciais para o desenvolvemento multicelular.
