In cells that stop dividing, transcription of proto-oncogenes is inhibited by the means of epigenetics. Proto-oncogenes are structured just like any other genes: there are regulatory regions such as enhancers and promoters, and there are transcribed regions such as introns and exons. Consider the following two scenarios: SCENARIO A: By the means of hydroxylation of methyl groups bound to DNA in the promoter region, you eliminated transcriptional control of the gene. SCENARIO B: By the means of Cripr-Cas9 you introduce “TAA” in the exon, which successfully eliminates translation of the transcribed product. SCENARIO A mutation is: a) gain-of-function, dominant b) loss-of-function, dominant c) gain-of-function, recessive d) loss-of-function, recessive SCENARIO B mutation is: a) gain-of-function, dominant b) loss-of-function, dominant c) gain-of-function, recessive d) loss-of-function, recessive • Show less
