Question

The length of an entire copy of the human genome (n) is

a. 3.3 billion base pairs which equals approximately 1 meter in length
b. 3.3 billion base pairs which equals approximately 1 centimeter in length
c. 1.1 billion base pairs which equals approximately 1 meter in leangth
d. 1.1 billion base pairs which equals approximately 1 centimeter in length

Answer 1

The human genome, which consists of roughly 3.3 billion base pairs, reaches a length of about 2 meters when stretched out. This was confirmed through the Human Genome Project completed in 2003.

Step-by-step explanation:

The entire copy of the human genome comprises approximately 3.3 billion base pairs. If one were to lay out the DNA from all 46 chromosomes end-to-end, it would stretch out to approximately 2 meters.

This immense length needs to be packaged efficiently within the microscopic space of a cell nucleus.

The Human Genome Project, which was a landmark international scientific research project completed in 2003, determined this by sequencing all of the DNA base pairs contained within the human genome.
