Re: [DIYbio] Re: Genomics and Next Generation Sequencing course in Silicon Valley

Yes they have compared whole genomes not only from existing apes but also from ancient humans (neanderthals, etc.) with modern humans. 
There has been quite a bit of focus on genes that are different from other apes to figure out what are "human" genes (http://science.sciencemag.org/content/360/6393/eaar6343). Also another interesting discovery is that RNA splice forms are quite different even though the gene is essentially the same (https://www.ncbi.nlm.nih.gov/pubmed/28957512). We are still scratching the surface of genomics! Pretty exciting time!
BTW, percentages are not useful metrics when the numbers are large. For example, about 1-2% of our genome codes for proteins. So a metric such as 1% difference in chimps and humans does not mean much because that 1% difference may all be in coding genes - this is not true of course - but just to give you a sense of how numbers can mislead. Another example of percentages being misleading is anti-bacterial soaps etc that say that 99% of bacteria are eliminated. the amount of original bacteria may be 10e7. So if I have got rid of 99% I still have 1,000,000 bacteria remaining!

Hello,

have they compared more than 1% of human and chimpanzee DNA already?

Also I dont find anywhere, how many percent is chimp DNA already sequenced.

As here only 1.9 million base pairs was compared, it is about 0.06% of the whole genome. Why only so little can be compared?

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC379137/

Also this is noteworthy:

"98.6% sequence identity drops to only 86.7% taking into account the multiple insertions/deletions (indels) dispersed throughout the region. "
