The correct answer is
D) no change in the amino acid sequence of a protein
Silent mutations are base substitutions that result in no change of the amino acid or amino acid functionality when the altered messenger RNA (mRNA) is translated.Silent mutations can also be produced by insertions or deletions, which cause a shift in the reading frame.

1. If an mRNA carried a mutation that caused a difference in the amino acid sequence relative to the wild-type gene product, would the translation machinery recognize this and correct it? Explain. 2. Synthesis of mRNA (transcription) and protein (translation) proceed in an ordered manner, from one end of the molecule to another. What is the polarity of each of these processes? (Use the terms 5', 3', amino, carboxyl.)

Dystrophin is a protein that forms part of a vital protein complex that connects the cytoskeleton of a muscle fiber cell to the extracellular matrix. This connection strengthens and shapes the muscle fibers. Dystrophin is coded by the DMD gene. This is one of the longest human genes known, covering 2,300,000 base pairs (0.08% of the human genome) It is located in chromosome 21. The immature mRNA is 2,100,000 bases long and takes 16 hours to transcribe. It contains 79...
