2.) Consider the following RNA sequence, which represents thebeginning of an open reading frame: 5’-AUGGGACUAGAUACC-3’. Examineeach of the sequences below, describe the change to the sequence,and state whether it represents a silent, missense, nonsense, orframeshift mutation. If frameshift, be sure to include theconsequences of the frameshift (nonsense or massive missense). Usethe codon table. a) 5’-AUGGGUCUAGAUACC-3’ b) 5’-AUGCGACUAGAUACC-3’c) 5’-AUGGGACUAGUUACC-3’ d) 5’AUGGGACUAAGAUACC-3’ 3. Using a coupleof sentences each, describe the function of each of the followingin regulating eukaryotic gene expression: a) promoter b) enhancerc) histone acetyltransferase d) 5-methylcytosine
