Question

How many base pairs does the human genome contain?

Options

• About 5 billion base pairs

• About 3 billion base pairs

• About 10 billion base pairs

• About 1 billion base pairs

Answer 1

The human genome contains approximately 3 billion base pairs. This enormous number of base pairs represents the total length of DNA in a human cell and was a central focus of the Human Genome Project, which aimed to determine the sequence of all these base pairs and map the genes they contain.
