QUESTION #1 What was the pre-genome sequencing estimate for the total number of genes in the human genome and how many genes were discovered once sequencing was complete? Why do you think there was such a discrepancy between these numbers? QUESTION #2 Why is looking for regions of the genome that are very similar across organisms (conserved) such an important part of understanding genome evolution?
