Proteins that bind both DNA and RNA typify the ability of a single gene product to perform multiple functions. Such DNA- and RNA-binding proteins (DRBPs) have unique functional characteristics that stem from their specific structural features; these developed early in evolution and are widely conse...
This article is on the Structure of DNA & RNA. Understand the structure of DNA and RNA in detail. Along with proteins, lipids and complex carbohydrates (polysaccharides), nucleic acids are one of the four main types of macromolecules necessary for all known life forms. Nucleic acids are compos...
cells and many viruses. It consists of two strands of nucleotides linked together in a structure resembling a ladder twisted into a spiral. In eukaryotic cells, the DNA is contained mainly in the nucleus and mitochondria. DNA can replicate itself and synthesize RNA. CompareRNA. See Note atgene...
Structure comparison and alignment are of fundamental importance in structural biology studies. We developed the first universal platform, US-align, to uniformly align monomer and complex structures of different macromolecules—proteins, RNAs and DNAs. The pipeline is built on a uniform TM-score object...
The PDB archive is jointly managed by the Worldwide Protein Data Bank partnership, involving data centers in the United States, Europe and Asia. It contains more than 160,000 3D structures for proteins, DNA, and RNA.
Biomolecule, any of numerous substances that are produced by cells and living organisms. Biomolecules have a wide range of sizes and structures and perform a vast array of functions. The four major types of biomolecules are carbohydrates, lipids, nucleic
7.1.2 Outline the structure of nucleosomes. Nucleosomes consist of DNA wrapped around eight histone proteins and held together by another histone protein. 7.1.3 State that nucleosomes help to supercoil chromosomes and help to regulate transcription. ...
Gene, unit of hereditary information that occupies a fixed position on a chromosome. Genes achieve their effects by directing the synthesis of proteins. They are composed of deoxyribonucleic acid (DNA), except in some viruses, which have genes consisting
The structure of DNA differs from that of RNA in that the structure of DNA contains the sugar deoxyribose while that of RNA contains the sugar ribose...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your toug...
Since the central dogma was proposed in 1950, the main role attributed to RNA has been to act as the intermediate between DNA and protein synthesis. Yet, more than 70% of the genome is transcribed and just a small part codes for proteins1,2, which indicates that the majority of RNAs cou...
