Having extracted the BRCA1 and BRCA2 genes from human DNA to isolate them as a research subject, Myriad Genetics feels it is entitled to its patent on the new DNA compound, but petitioners in a Supreme Court case are contesting it on the grounds that a company cannot copyright nature.
Too many pronouns here, I am confused. What are "them","it", and "it" referring to? Let's rephrase the sentence to make it clear:
Having extracted the genes from human DNA to isolate "the genes" as a research subject, Myriad Genetics feels "Myriad Genetics" is entitled to "Myriad Genetics' " patent on the new DNA compound, but petitioners in SC case are contesting "the patent" on the grounds that a company cannot copy right nature.
Other than the confusion, I don't know what is wrong with the sentence. So let's check the answer choice and figure out.
(A) Having extracted the BRCA1 and BRCA2 genes from human DNA to isolate them as a research subject, Myriad Genetics feels it is entitled to its patent on the new DNA compound
Keep A for now since I don't see the clear errors yet.
Hmmmmm. All pronouns are the same as A. What is going on here? "having had extracted" - Why do we use past perfect tense here? The whole sentence uses only present tense. This can't be right. B is out.
Yay, I found the error. "It" can't refer back to "the genes. C is out.
(D) Having extracted the BRCA1 and BRCA2 genes from human DNA to isolate them as research subjects, Myriad Genetics now feels it is entitled to its patents on the new DNA compounds
Yay another one, given "it" is referring back to "patents". D is out.
(E) Having extracted the BRCA1 and BRCA2 genes from human DNA to isolate them as research subjects, Myriad Genetics now feels entitled to its patents on the new DNA compound
Same as D. E is out.
So only A is left. A must be the correct answer.
