Oh.. i see. thanks alot:)

Hello, everyone. I have a silly question about human genetics. I was a clinical laboratory science undergraduate student, and i haven't take any class of molecular biology or genetics, so i'm afraid i'm going to ask a question that may be silly. I was watching the show about 100 discoveries over the past century by the discovery channel, and when i watched the genetics part, at the end of it, it was about human genome project. The head scientist said that human has about 26000 genes. and i have one question that has bothering me since i watched the documentary. how to know that human has 26000 genes? from the little knowledge i gathered from general biology. the genes are a piece of nucleic acids. how to find out human has 26000 genes? won't a piece of genes may be a piece of nucleic acids that are from different parts along the DNA sequence of the chromosome? (my native language is not English, so if i made many mistakes in writing my question, i apologize. ) Thank you all.
