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

B. Having had extracted the BRCA1 and BRCA2 genes from human DNA to isolate them as research subjects, Myriad Genetics now feels it is entitled to its patent on the new DNA compound

C. Having extracted the BRCA1 and BRCA2 genes from human DNA to isolate it as a research subject, Myriad Genetics now feels it is entitled to its patent on the new DNA compound

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

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

OFFICIAL SOLUTION

Difficulty Level: 750-800

A. This difficult Pronoun Agreement problem is also evidence that ‘The Whole Sentence Matters’.

Choice B is incorrect for Tense reasons, as no existing past-tense verb exists to justify “having had extracted”.

And C is incorrect for a Pronoun Agreement error, as “to isolate it…” refers to two different genes, making “it” incorrect.

Choices D and E are wrong for a more subtle reason – after the underline, the singular pronoun “it” refers to “its patent” (singular), meaning that “its patents”(plural) in D and E are incorrect.

Accordingly, the correct response is A.

Guys....IMO D is the correct answer.

(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

(B) Having had extracted the BRCA1 and BRCA2 genes from human DNA to isolate them as research subjects, Myriad Genetics now feels it is entitled to its patent on the new DNA compound

(C) Having extracted the BRCA1 and BRCA2 genes from human DNA to isolate it as a research subject, Myriad Genetics now feels it is entitled to its patent on the new DNA compound

(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

(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

We need to focus on the meaning here. After extracting B1 & B2 , the DNA is the new DNA compound. So "it " refers to the new DNA and only D fits .

The sentence says - petitioners in a Supreme Court case are petitioning 'it'. Hence, the pronoun 'it' should refer to 'patent' and not to 'patents'. Eliminate D and E.

Eliminate B for the use of 'Having had'.

Eliminate C for a subtle error. The subject of the sentence is genes, which have been isolated. Hence, 'them' should be used instead of 'it'.
