Summary Introduction
To describe: Some of the processes that contribute to genome evolution.
Introduction: The genome evolution is the process by which the genome changes in size or structure over the evolutionary time. The common basis of change at the level of genome is mutation, which underlies much of genome evolution.

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?arrow_forward
