DNA for Beginners, republished as DNA: A Graphic Guide to the Molecule that Shook the World, is a 1983 graphic study guide to DNA written by Professor Israel Rosenfield from the City University of New York with Professor Edward Ziff from the New York University School of Medicine, and illustrated by Borin Van Loon.
Who We Are and How We Got Here is a 2018 book on the contribution of genome-wide ancient DNA research to human population genetics by the geneticist David Reich.He describes discoveries made by his group and others, based on analysis and comparison of ancient and modern DNA from human populations around the world.
DNA exists in many possible conformations that include A-DNA, B-DNA, and Z-DNA forms, although only B-DNA and Z-DNA have been directly observed in functional organisms. [14] The conformation that DNA adopts depends on the hydration level, DNA sequence, the amount and direction of supercoiling, chemical modifications of the bases, the type and ...
Molecular evolution describes how inherited DNA and/or RNA change over evolutionary time, and the consequences of this for proteins and other components of cells and organisms. Molecular evolution is the basis of phylogenetic approaches to describing the tree of life .
Left: unchanged DNA strand. Right: DNA strand intercalated at three locations (black areas). In biochemistry, intercalation is the insertion of molecules between the planar bases of deoxyribonucleic acid (DNA). This process is used as a method for analyzing DNA and it is also the basis of certain kinds of poisoning.
Dawkins builds upon George C. Williams's book Adaptation and Natural Selection (1966), which argued that altruism is not based upon group benefit per se, [4] but results from selection that occurs "at the level of the gene mediated by the phenotype" [5] and that any selection at the group level occurred only under rare circumstances.

A couple has been arrested after authorities say they performed a botched circumcision on their son at their central Missouri home last week.. Prosecutors charged Tyler Wade Gibson, 35, with one ...
Mitochondrial DNA is a small portion of the DNA contained in a eukaryotic cell; most of the DNA is in the cell nucleus, and, in plants and algae, the DNA also is found in plastids, such as chloroplasts. [3] Human mitochondrial DNA was the first significant part of the human genome to be sequenced. [4]
