The post 50 Hilarious Science Memes From “A Place Where Science Is Cool” (New Pics) first appeared on Bored Panda. ... the 1953 paper on the structure of DNA by James Watson and Francis Crick ...
The A form occurs under non-physiological conditions in partly dehydrated samples of DNA, while in the cell it may be produced in hybrid pairings of DNA and RNA strands, and in enzyme-DNA complexes. [54] [55] Segments of DNA where the bases have been chemically modified by methylation may undergo a larger change in conformation and adopt the Z ...
Ribonucleic acid (RNA) is a polymeric molecule that is essential for most biological functions, either by performing the function itself (non-coding RNA) or by forming a template for the production of proteins (messenger RNA). RNA and deoxyribonucleic acid (DNA) are nucleic acids. The nucleic acids constitute one of the four major ...
Nucleic acids RNA (left) and DNA (right). Nucleic acids are large biomolecules that are crucial in all cells and viruses. [ 1 ] They are composed of nucleotides, which are the monomer components: a 5-carbon sugar, a phosphate group and a nitrogenous base. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid ...
Directionality (molecular biology) A furanose (sugar-ring) molecule with carbon atoms labeled using standard notation. The 5′ is upstream; the 3′ is downstream. DNA and RNA are synthesized in the 5′-to-3′ direction. Directionality, in molecular biology and biochemistry, is the end-to-end chemical orientation of a single strand of ...
Threose nucleic acid (TNA) is an artificial genetic polymer in which the natural five-carbon ribose sugar found in RNA has been replaced by an unnatural four-carbon threose sugar. [1] Invented by Albert Eschenmoser as part of his quest to explore the chemical etiology of RNA, [2] TNA has become an important synthetic genetic polymer (XNA) due ...
Contents. History of RNA biology. Numerous key discoveries in biology have emerged from studies of RNA (ribonucleic acid), including seminal work in the fields of biochemistry, genetics, microbiology, molecular biology, molecular evolution, and structural biology. As of 2010, 30 scientists have been awarded Nobel Prizes for experimental work ...
MEME. M ultiple E xpectation maximizations for M otif E licitation (MEME) is a tool for discovering motifs in a group of related DNA or protein sequences. [ 1] MEME takes as input a group of DNA or protein sequences and outputs as many motifs as requested up to a user-specified statistical confidence threshold.
