The linearized double helix distributed in the matrix more evenly and forms electric fields more strong, while those circled but with nicked double helix more aggregated with electric fields hardly formed. The migration of linearized double helix therefore becomes fast, while circled with nicked double helix slow significantly in the electrophoresis.Anonymoushttps://www.blogger.com/profile/11258942440378850164noreply@blogger.comtag:blogger.com,1999:blog-7315236707728759521.post-54697870739090586412016-01-27T01:35:52.978-07:002016-01-27T01:35:52.978-07:00As I note, it may very well not be a steppe origin...As I note, it may very well not be a steppe origin. It could just as easily be that Iberian women married migrating Bell Beaker men whose clans were extremely successful and road that founders effect. Or it could be that the village or region that was the source of the Western European Bell Beakers happened to be rich in mtDNA H relative to the steppe as a whole. There are lots of viable scenarios. But, the two phenomena are almost surely related in some manner or another.andrewhttps://www.blogger.com/profile/08172964121659914379noreply@blogger.comtag:blogger.com,1999:blog-7315236707728759521.post-62061897066435844122016-01-26T20:08:26.594-07:002016-01-26T20:08:26.594-07:00The ancient mtDNA situation for Europe is very con...The ancient mtDNA situation for Europe is very confusing. I discuss this situation at my blog: http://mtdnaatlas.blogspot.com. <br /><br />Here's why I think it's unlikely "Steppe" is an important source of H1/H3.<br /><br />>It is unlikely "Steppe" is a important source of H or H1+H3 in modern Europe. We have lots of mtDNA from "Steppe"(Yamnaya, Catacomb, Corded Ware, Andronvovo/Sintashta). They had on average 20-25% H. All Yamnaya/Catacomb were tested for H1/H3, and only 2/27 had H1 and 0/27 had H3. <br /><br />>It is more likely Neolithic/EEF is an important source of H1/H3. A decent frequency of Neolithic H tested for H1/H3 are positive. From a particular site in Early Neolithic France it had modern-like frequencies of H and H1/H3. <br /><br />>The mtDNA H in pre-Neolithic Iberia isn't confirmed. They're from old studies have several strange results that I can explain if you want. If they're legit, that's big news. Hopefully someone will do more testing from pre-Neolithic Iberia.
