Homework Answers
1. Silent mutation = A change in the
DNA sequence does not alter the amino acid sequence
These mutations do not alter the protein function
Ex: GGG ----> GGU: Both codons specify the same amino acid,
Glycine.
2. Promoter = Binding site for the RNA polymerase to initiate
transcription
It is located upstream to the transcription start site
i.e. 5'-end of the coding strand (or) 3'-end of the template
strand

QUESTION 13 Based on Figure 9-24, can you predict the position of a mutation that would produce an active protein that was not directed out of the cell for secretion? ER lumen Signal sequence Cytosol ER membrane 2015 A mutation in the NLS would cause a normally secreted protein to stay inside the cell. A mutation in the 3' UTR would produce an active but improperly secreted protein. A mutation in the ribosome would produce an active but improperly located...

Genetics Worksheet Week 3: Gene Regulation and Epigenetics 1. Duchenne muscular dystrophy is caused by a mutation in a gene that is 2.5 million nucleotides in length and encodes a protein called dystrophin. The dystrophin protein itself is 3684 amino acids in length. Calculate below the approximate size of the mRNA that encodes dystrophin. Approximately what percentage of the gene that encodes dystrophin is intron sequence? The human genome encodes a much greater variety and number of proteins than the...
