Question
The human genome project was an international effort to completely map the all of the genes of humans. The
first information on the human genome generated from this endeavor was published in 2000 and the full
sequence was published in 2003. Since then, estimates of the rumber of genes in the human genome have
steadily declined, and it is now though that there are about 20,500 genes in the human genome, but the
exact number is yet to be determined.
Since we have known the sequence of the human genome for almost two decades, why are scientists still not
sure of the total number of genes contained within the human genome? In other words, why is it taking so
long to determine the number of genes humans have?
