Group of answer choices a)transcription b)translation c)mRNA splicing d)All of the above e)transcription and translation only 2)Which of the following is the least likely mechanism to convert a proto-oncogene to an oncogene? Group of answer choices a)gene amplification b)point mutation within the gene c)point mutation in the promoter or enhancer regions d)histone acetylation e)chromosome translocation

Regulation of Gene Expression in Eukaryotes In all organisms, certain genes are expressed at any given time while other genes are not. Both prokaryotes and eukaryotes regulate gene expression at the transcription stage. However the greater complexity of eukaryotic cells makes it possible for gene expression to be regulated at many other stages as well. The diagram below shows different stages at which gene expression may be regulated in eukaryotes. nucleus chro modifica anscription RNA processing cytoplasm degradation protein processing...
