Using this DNA molecule, answer the following questions Sense:——A T G G G A T A T T G A Anti-Sense: T A C C C T A T A A C T   a. Perform transcription and write the sequence of the correct RNA strand b. Identify where in the cell transcription takes place c. using the codon table below, translate the amino acid code d. Identify where in the cell translation takes place e. If there is a mutation in the Sense Strand that changes the codon  A T G G G A T A T T G A to  A T G G G U T A T T G A, what type of mutation would this cause, and how would it affect the protein functionality?
