As a researcher in a protein lab, you analyze two different proteins for their shape and the amino acids they contain. your results show that the two proteins have exactly the same numbers and types of amino acids, but they have different shapes. what is the best explanation for these results?

While the proteins have the same number and type of amino acids, their shape is different because each of them has a unique sequence of amino acids.

Explanation:

Proteins are made up of amino acids. The sequence of these amino acids actually determines the functions and overall composition of the protein. This also has a direct impact on how protein reacts with it's environment e.g. within our bodies during digestion. Hence, while two protein samples have similar number and types of amino acids, their shapes are different.

Amino acids are further broken down into hydrogen, carbon, oxygen and nitrogen molecules. They way these atoms are arrange further impacts the composition and function of the amino acids.

as university of miami psychologists debra lieberman and adam smith pointed out in a recent article in the journal current directions in psychological science, humans have social and psychological mechanisms to deter incest. with very few exceptions, marriages between brothers and sisters and between parents and their children are verboten in every human culture. the primary psychological anti-incest mechanism is the yuck response. even the idea of sex with their mom or dad, bro or sis is upsetting to most people. the psychologist jonathan haidt has found that nearly everyone is repelled by the prospect of brother-sister sex, even in hypothetical situations in which there is no chance of pregnancy).

the biological cost of incest

this raises an interesting question: just what’s so bad about incest? sure, having sex with your dad or your sister seems gross — but why? some anthropologists have argued that incest taboos are learned social conventions. this explanation, however, doesn’t make sense to me as it does not explain the widespread existence of anti-incest mechanisms in creatures ranging from cockroaches to chimpanzees. second, the incest taboo is about as close to a universal law as human moral rules get.

why should mechanisms to avoid incest be so widespread both in nature and across human societies? the answer is simple. the problem with having sex close with relatives is that there is an astonishingly high chance that your offspring will be born with a serious birth defect.
