The human genome contains approximately 3 billion of these base pairs, which reside in the 23 pairs of chromosomes within the nucleus of all our cells. Each chromosome contains hundreds to thousands of genes, which carry the instructions for making proteins.
Q. How did all life begin?
Many scientists believe that RNA, or something similar to RNA, was the first molecule on Earth to self-replicate and begin the process of evolution that led to more advanced forms of life, including human beings.

Q. Who owns the human genome?
NHGRI, an agency of the National Institutes of Health, works with the Joint Genome Institute of the U.S. Department of Energy in coordinating the U.S. portion of the HGP, a 15-year program funded by the government and nonprofit foundations.
Q. How much of human genome is patented?
A previous analysis of patented genes carried out in 2005 estimated that 18% of known genes in the human genome were patented [10], but a recent study suggested that this estimate could be inflated as some sequences are not found in the patents’ claims [8].
Q. How many human genomes have been sequenced?
The second data set was obtained from the publicly funded Human Genome Project and was derived from the BAC contigs (called bactigs); here, Celera “shredded” the Human Genome Project DNA sequence into 550-base-pair sequence reads representing a total of 16.05 million sequence reads.
Q. Do we know the entire human genome?
“The human genome has not been completely sequenced and neither has any other mammalian genome as far as I’m aware,” said Harvard Medical School bioengineer George Church, who made key early advances in sequencing technology.
Q. Why would someone want their DNA sequenced?
The sequence tells scientists the kind of genetic information that is carried in a particular DNA segment. For example, scientists can use sequence information to determine which stretches of DNA contain genes and which stretches carry regulatory instructions, turning genes on or off.
