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.
DNA can be copied very easily and accurately because each piece of DNA can direct the assembly of a new copy of its information. This is because DNA is made of two strands that pair together like the two sides of a zipper. The nucleotides are in the center, like the teeth in the zipper, and pair up to hold the two strands together.
Genetic genealogy is the use of genealogical DNA tests, i.e., DNA profiling and DNA testing, in combination with traditional genealogical methods, to infer genetic relationships between individuals. This application of genetics came to be used by family historians in the 21st century, as DNA tests became affordable.

Personal genomics or consumer genetics is the branch of genomics concerned with the sequencing, analysis and interpretation of the genome of an individual. The genotyping stage employs different techniques, including single-nucleotide polymorphism (SNP) analysis chips (typically 0.02% of the genome), or partial or full genome sequencing.
When I sent DNA samples to genetic testing services searching for my birth family, I had no idea it would launch me on an adventure across three continents. In 1961, I was adopted at birth in ...
DNA is a mixture of genetic material ‒ some inherited from one parent, some from the other – so it can reveal the full make up of someone's genetic inheritance.
Population genetics is a subfield of genetics that deals with genetic differences within and among populations, and is a part of evolutionary biology.Studies in this branch of biology examine such phenomena as adaptation, speciation, and population structure.
