12.1: DNA Structure. In the 1950s, Francis Crick and James Watson worked together to determine the structure of DNA at the University of Cambridge, England. Other scientists like Linus Pauling and Maurice Wilkins were also actively exploring this field. Pauling had discovered the secondary structure of proteins using X-ray crystallography.
13.1: Introduction to DNA Structure and Function. The three letters “DNA” have now become synonymous with crime solving, paternity testing, human identification, and genetic testing. DNA can be retrieved from hair, blood, or saliva. Each person’s DNA is unique, and it is possible to detect differences between individuals within a species ...
This page titled 8.3: DNA Structure is shared under a CC BY license and was authored, remixed, and/or curated by Gerald Bergtrom. By 1878, a substance in the pus of wounded soldiers derived from cell nuclei (called nuclein) was shown to be composed of 5 bases (the familiar ones of DNA and RNA). The four bases known to make up ….
Our genetic information is coded within the macromolecule known as deoxyribonucleic acid (DNA). DNA belongs to a class of organic molecules called nucleic acids. The building block, or monomer, of all nucleic acids is a structure called a nucleotide. A nucleotide has three parts: phosphate, deoxyribose sugar, and a nitrogen base.
14.3: Basics of DNA Replication. The elucidation of the structure of the double helix provided a hint as to how DNA divides and makes copies of itself. This model suggests that the two strands of the double helix separate during replication, and each strand serves as a template from which the new complementary strand is copied.
Hace 3 días · Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and ...
