Final answer:
Option B: The Supreme Court case that ruled naturally occurring DNA segments cannot be patented is Association for Molecular Pathology v. Myriad Genetics, Inc.
Step-by-step explanation:
The Supreme Court case that held that a naturally occurring DNA segment cannot be patented is Association for Molecular Pathology v. Myriad Genetics, Inc.. This landmark decision made it clear that while synthetic DNA sequences, or cDNAs, could be patented due to the fact that they are not naturally occurring, naturally occurring segments of DNA that are merely isolated from the body cannot be patented.
This was a significant ruling that impacted both the legal and scientific communities, as it determined that genetic material found in nature is not patent eligible. The Supreme Court case that held that a naturally occurring DNA segment cannot be patented is Association for Molecular Pathology v. Myriad Genetics, Inc.
