Answers study questions 19 1. Rank the following mutations according to the damage potential toward the function of a gene frameshift = nonsense > missense > first (codon) position changes > third (codon) position changes 2. In an extraterrestrial creature investigated at area 51 the genetic code has a single unique codon for each amino acid, and the rest of the possible codons specify stop signals. Com- pared to our code, this code is less efficient because it maximizes deleterious consequences from mutations a. less efficient, maximizes deleterious Note that in our code a change in a third position nucleotide is likely not to change the amino acide encoded, and rarely will it yield a stop codon. In the area 51 creature, however, any change will change the amino acid and very frequently it would actually result in a stop codon Yam tuber is a potato-like food produced from the root of the yam plant. To plant a field of yams, farmers use sprouted cuttings from the yam tuber. 3. If you take a single tuber from a starting plant heterozygous at several loci, split it into 6 sec-
