1. In the movie, the physicians are not portrayed in a good light. A movie reviewer in the journal Nature (Rosen, 1993) said that the movie portrayed "nurses as heartless, physicians pompous fools and parent support groups as mindless as a herd of sheep." Is this what is called "artistic license" to make you cheer for the Odones? What were the objections of the physicians and reasons for their objections? Were the objections reasonable? Was it appropriate for the Odones to use themselves as "guinea pigs?" and could this have done more harm than good? Doctors warned the Odones that erucic acid would cause heart problems (as it does in laboratory animals); the Odones countered with the fact that East Asians eat rapeseed oil daily.

Considering the yellow and green pea color phenotypes studied by gregor mendel: a. what is the biochemical function of the protein that is specified by the gene responsible for the pea color phenotype? (1 point) b. a null allele of a gene is an allele that does not specify (or encode) any of the biochemical function that the gene normally provides (in other words, either no protein at all or only non-functional protein is produced from it). of the two alleles, y and y, which is more likely to be a null allele? (1 point) c. in terms of the underlying biochemistry, why is the y allele dominant to the y allele? (2 points) d. why are peas that are yy homozygotes green? (1 point) e. the amount of protein produced from a gene is roughly proportional to the number of functional copies of the gene carried by a cell or individual. what do the phenotypes of yy homozygotes, yy heterozygotes, and yy homozygotes tell us about the amount of sgr enzyme needed to produce a yellow color? explain your reasoning.
