DNA 99% Human

[hiflier]

So what exactly is it that a scientist would look for? With all the talk about nucleotides, base pairs, etc. what would a Sasquatch sequence that isn't quite Human look like? What is it in the DNA that set it apart? I mean, we all pretty much know that that DNA, either in its cell nucleus or its mitochondria, is identified by four letters A, T, C, or G. It is precisely what it means.....PAIRING.

 

"A" always pairs with "T" and "C" always pairs with "G". And as a base pair, "A-T" can either be "A-T" or "T-A". And the "C-G" pair can also pair as "G-C."

 

When one looks at a sequence, they will see (for example) CGGCATATTATAGCCGTA where every letter represents one half of its base pair. The other half (not shown) will automatically be GCCGTATAATATCGGCAT. Because of the way the letters pair up, a geneticist only needs  one string of letters in order to know that the opposite letter is present. In the Human mitochondrial DNA there are 16,569 of those base pairs. But each species or genus has its own sequence so, with current sequencers, matching strings of A-T, C-G is pretty easy. The entire 16,569 Human base-pair sequence is well known and so deviations between, say, Humans and Chimps will be obvious. So, what's up with the Sasquatch? Its DNA maybe not be so obvious. But there WILL be differences.

 

A degraded sample may not show those differences, however, unless one gets very lucky with the quality of the sample. It will be much easier to tell the difference between Humans and Sasquatches if the entire mtDNA sequence is there for comparison. Fragments are just that, fragments. And with those fragments, even if they belong to the Sasquatch, there may not be enough information to know where those fragment plugs into the full Human DNA sequence to detect any differences.

........ It was a 2-hour documentary about an expedition to the Himalayas.  Along with DNA tests of tracks, they took samples of water from a pristine stream.  This was such a high elevation that it was unlikely there was any human evidence to found in the stream.  They announced the results of the stream water samples.  There was found DNA from local animals, but there was also DNA that was "99% human."...........What could explain the 99% human DNA?........

.......contrary to popular belief, the captain of the plane does not have the ability to detach the toilet tank and send it plummeting mid-flight. (When people report “blue ice” falling from above, it is usually just a leak of the sewage tank or drain tube that freezes to the aircraft.).........

HA, HA, HA!! Good one Hunster, Human DNA is pretty much everywhere at this point.
