Many genes important in development are regulated by effecting their mRNA. What is the mechanism responsible for this regulation? DNA methylation phosphorylation of amino acids histone modifications RNA interference
Which of the following is true only for eukaryotic gene expression? mRNA is synthesized in the 3' ---> 5' direction. Translation of mRNA routinely begins before transcription is complete.
