When did the Human Genome Project begin and end?

• A. 1980 to 1995
• B. 1990 to 2003
• C. 2000 to 2010
• D. 1975 to 1985

Answer: (B)

The Human Genome Project was an international scientific research initiative aimed at mapping and understanding all the genes of the human species. It officially began in 1990 and was completed in 2003, making this timeframe significant for several reasons.

This project was monumental as it sought to sequence the three billion base pairs of human DNA and identify all human genes. The completion of the project in 2003 marked a pivotal moment in genetics and biotechnology, providing a foundational blueprint for studying genetic diseases, developing new therapies, and advancing our understanding of human biology.

The other timeframes listed do not align with the established historical record of the Human Genome Project. Years preceding 1990 lacked the technological advancements necessary for such an ambitious initiative, and the timeframe extending into the 2000s doesn't fit, as the project was officially concluded by 2003. Therefore, the correct answer reflects the accurate period during which this groundbreaking research was conducted.
