DNA and RNA are the two primary types of nucleic acids. DNA and RNA differ in their sugar component, the types of nucleotides they contain and the number of strands of nucleotides they have. Nucleotides The nucleotides that form nucleic acids are divided into two groups: pyrimidines and purine...
Cells containDNA(deoxyribonucleic acid) andRNA(ribonucleic acid), the genetic information necessary for directing cellular activities. DNA and RNA are molecules known asnucleic acids. In prokaryotic cells, the single bacterial DNA molecule is not separated from the rest of the cell but coiled up in...
More recently, it is appreciated that nucleosome remodelling is neutral with respect to the structural transitions it brings about; nucleosome can be moved to uncover a stretch of DNA, or to close a gap in the regular succession of nucleosomes that may pose a risk for chromosome breakage. ...

Nucleic acids include DNA and ribonucleic acid (RNA). Nucleic acids, along with proteins, lipids, and complex carbohydrates (polysaccharides), are one of the four primary macromolecules required for all known life forms. See the fact file below for more information on DNA and Inheritance or ...
Learn about proteins, a type of organic molecule. Discover how amino acids create proteins, what parts of the body are made of protein, and what foods provide the body with protein. What's a Protein? Have you ever wondered how professional wrestlers, circus acrobats, and Olympic athletes get...
Lipids are large, diverse molecules linked by the property of being insoluble in water. Along with proteins, carbohydrates and nucleic acids, lipids are one of the four main types of organic macromolecules necessary for life’s functioning.
effect of polar groups, thus avoiding the necessity of an inherently chiral surface for enantioselection (Bielski and Tencer2007). Likewise, a favorable puckered conformation for the β-D-ribose anomer has been invoked to justify ribose’s selection in nucleic acids, while for the other pentoses...
