1. What would happen to a gene if the stop codon (UAA, UAG, or UGA) were mitated so that the first position in the codon became a “C” (CAA, CAG, CGA)? a) the protein product of the gene would be similar than normal b) either the immature RNA transcript or the mRNA will be degraded by nonsense mediated RNA decay c) its mature messenger RNA would be lengthened d) its immature RNA would be lengthened 2. Without a promoter region,...

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...
