Answer:
The correct option is "the exact location of a particular disease-causing gene can be determined."
Step-by-step explanation:
The discovery of the human genome will let us know the sequence of normal genes in a human. By comparing to this sequence, one can easily know if there is any abnormality in the fetus. The exact location where a fault has occurred can be recognized if the sequence of the normal human genome is known. Hence, the discovery of the human genome is very beneficial to the process of amniocentesis.
