Explore the double helix structure, such as the width of a DNA strand. See the history of the DNA strand model and who discovered the double helix model of DNA.
Understanding the Context
The discovery of DNA is the foundation of all research in molecular biology. Learn the facts about the discovery of DNA, its structure, and the function of DNA in heredity.
DNA is found in the nucleus, condensed and wrapped around proteins into a structure called chromatin. Upon cell division, chromatin undergoes further condensation to form chromosomes.
Nucleic acids are in the form of DNA and RNA and are important for cell structure and function. What is a phosphodiester bond in biology?
Nucleic acids are large biomolecules used to store, transfer and convey genetic information in cells. Explore the structure of nucleotides and what polynucleotide and phosphodiester bonds do ...
