The main achievement of the Human Genome Project was
Correct answer: B. determining the complete base sequence of human DNA
- A. curing all inherited diseases
- B. determining the complete base sequence of human DNA
- C. producing the first cloned human being
- D. creating an artificial human chromosome
Explanation
The project, completed in draft form in 2001, established the order of roughly three billion base pairs and located about twenty thousand protein coding genes. Knowing the sequence is the starting point for identifying disease genes, designing drugs and studying human evolution, but it is not itself a cure for anything. No human has been cloned, and doing so is banned in almost every country.
