Schematic illustration of maternal (mtDNA) gene-flow in and out of Beringia, from 25,000 years ago to present. The genetic history of the Indigenous peoples of the Americas is divided into two distinct periods: the initial peopling of the Americas from about 20,000 to 14,000 years ago (20–14 kya), [1] and European contact, after about 500 years ago.
The Roanoke (/ ˈ r oʊ ə ˌ n oʊ k /), also spelled Roanoac, were a Carolina Algonquian-speaking people whose territory comprised present-day Dare County, Roanoke Island, and part of the mainland at the time of English exploration and colonization.

[5] For a time, the Tutelo had a settlement on the banks of the New River. Many of the sherds collected there and the small triangular points, suggest a ...
There are two distinctive mapping approaches used in the field of genome mapping: genetic maps (also known as linkage maps) [7] and physical maps. [3] While both maps are a collection of genetic markers and gene loci, [8] genetic maps' distances are based on the genetic linkage information, while physical maps use actual physical distances usually measured in number of base pairs.

The double-helix model of DNA structure was first published in the journal Nature by James Watson and Francis Crick in 1953, [6] (X,Y,Z coordinates in 1954 [7]) based on the work of Rosalind Franklin and her student Raymond Gosling, who took the crucial X-ray diffraction image of DNA labeled as "Photo 51", [8] [9] and Maurice Wilkins, Alexander Stokes, and Herbert Wilson, [10] and base-pairing ...
