The amino acids for beta hemoglobin found in five species were compared to the amino acids found in human (homo sapiens) beta hemoglobin. the number of sequence differences was recorded. based on the molecular data, which species may be more closely related to humans? a) gorilla gorilla (gorilla) 1 b) hylobates lar (gibbon) 3 c) lemur catta (lemur) 30 d) macaca mulatta (rhesus monkey) 8

The correct answer should be option A.

It is because there is only one difference in the sequence of protein synthesized in the Gorilla gorilla and Homo sapiens.

As they have the least difference in the nucleotide or amino acid sequences of the protein they would the most closely related as compared to others.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

i was thinking 4.0 v hope this
