Which of the following were direct results of the Human Genome Project?
A) discovery of the genetic code
B) creation of PCR-based tests for many genetic diseases
C) the discovery that humans have approximately 20,000 genes—far fewer than expected
D) routine test for genetic forms of breast cancer
Select 3 correct options...
the genetic code had already been discovered
Oh, that makes so much sense. Thanks.
To determine which of the following options were direct results of the Human Genome Project, we need to understand the project itself and its goals. The Human Genome Project (HGP) was an international research effort that aimed to identify and map all the genes in the human genome and determine the sequence of DNA nucleotides that make up those genes.
A) Discovery of the genetic code: The genetic code was discovered before the Human Genome Project, so this is not a direct result of the project.
B) Creation of PCR-based tests for many genetic diseases: PCR (Polymerase Chain Reaction) is a technique used to amplify specific DNA sequences. The Human Genome Project provided crucial information about the location and sequence of many genes, allowing scientists to develop PCR-based tests for various genetic diseases. This is indeed a direct result of the project.
C) The discovery that humans have approximately 20,000 genes—far fewer than expected: The Human Genome Project helped scientists estimate the number of genes in the human genome. It was initially expected that humans would have significantly more genes, but the project revealed that the actual number is closer to 20,000. This discovery is a direct result of the project.
D) Routine test for genetic forms of breast cancer: The Human Genome Project provided essential genetic information that contributed to the development of tests for genetic forms of breast cancer. However, the specific phrasing "routine test" suggests that such tests are widely available and used regularly, which may not be the case. While the project contributed to advancements in this area, it may not directly result from the project itself.
Thus, the three correct options are B) creation of PCR-based tests for many genetic diseases, C) the discovery that humans have approximately 20,000 genes—far fewer than expected, and potentially D) routine test for genetic forms of breast cancer.
