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.
Deoxyribonucleic acid (DNA) is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms. The chemical DNA was discovered in 1869, but its role in genetic inheritance was not demonstrated until 1943. The DNA segments that carry this genetic information are called genes.
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.
When it comes to insects' DNA, humans have a bit less in common. For example, fruit flies share 61 percent of disease-causing genes with humans, which was important when NASA studied the bugs to ...
According to another study, when measured in a different solution, the DNA chain measured 22–26 Å (2.2–2.6 nm) wide, and one nucleotide unit measured 3.3 Å (0.33 nm) long. [10] The buoyant density of most DNA is 1.7g/cm 3. [11] DNA does not usually exist as a single strand, but instead as a pair of strands that are held tightly together.

DNA origami was the cover story of Nature on March 16, 2006. [3] Since then, DNA origami has progressed past an art form and has found a number of applications from drug delivery systems to uses as circuitry in plasmonic devices; however, most commercial applications remain in a concept or testing phase.
