nucleic
nucleic, a. Chem. (njuːˈkliːɪk, -ˈeɪɪk, ˈnjuːklɪɪk) [f. nucle-us + -ic.] nucleic acid, any of the naturally occurring polynucleotides present in most cells (chiefly in the chromosomes and ribosomes), which either store genetic information or translate this into the structure of proteins; they fall i...

Nucleic acid - RNA Metabolism | Britannica
Nucleic acid - RNA Metabolism: RNA provides the link between the genetic information encoded in DNA and the actual workings of the cell. Some RNA molecules such as the rRNAs and the snRNAs (described in the section Types of RNA) become part of complicated ribonucleoprotein structures with specialized roles in the cell. Others such as tRNAs play key roles in protein synthesis, while mRNAs ...

Nucleic acid - Wikipedia
The term nucleic acid is the overall name for DNA and RNA, members of a family of biopolymers, [11] and is synonymous with polynucleotide. Nucleic acids were named for their initial discovery within the nucleus, and for the presence of phosphate groups (related to phosphoric acid). [12] Although first discovered within the nucleus of eukaryotic ...

Nucleic acid | Definition, Function, Structure, & Types
Dec 15, 2023nucleic acid, naturally occurring chemical compound that is capable of being broken down to yield phosphoric acid, sugars, and a mixture of organic bases (purines and pyrimidines). Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited ...

Nucleic acid double helix - Wikipedia
In molecular biology, the term double helix [1] refers to the structure formed by double-stranded molecules of nucleic acids such as DNA. The double helical structure of a nucleic acid complex arises as a consequence of its secondary structure, and is a fundamental component in determining its tertiary structure .The structure was discovered by ...

Stable nucleic acid lipid particle - Wikipedia
Stable nucleic acid lipid particles ( SNALPs) are microscopic particles approximately 120 nanometers in diameter, smaller than the wavelengths of visible light. They have been used to deliver siRNAs therapeutically to mammals in vivo. In SNALPs, the siRNA is surrounded by a lipid bilayer containing a mixture of cationic and fusogenic lipids ...

For how long and how cold should I perform ethanol/isopropanol precipitations of RNA or DNA? Precipitating nucleic acids using either isopropanol or ethanol is a very common operation, and I've read some very differen...
I always did mine at -80 C, but I never compared the results to other protocols ( _I don't fix what's not broken_ ). But, I was curious about the same thing, so I looked around. I found one paper discussing this: Paithankar and Prasad, Nuc Acids Res 19(6):1346 (1991) It shows that at low concentrati...

Nucleic Acids Research | Oxford Academic
Enzymes known as PylRS offer the remarkable ability to expand the natural genetic code of a living cell with unnatural amino acids. Currently, over 200 unnatural amino acids can be genetically encoded with the help of PylRS and its partner tRNA Pyl , enabling us to endow proteins with novel properties, or regulate protein activity using light or inducible cross-linking.

Nucleic Acid Amplification Tests (NAATs) | CDC
May 12, 2023Updates as of June 16, 2021. Clarified the differences between laboratory-based and point-of-care NAATs. A Nucleic Acid Amplification Test, or NAAT, is a type of viral diagnostic test for SARS-CoV-2, the virus that causes COVID-19. NAATs detect genetic material (nucleic acids). NAATs for SARS-CoV-2 specifically identify the RNA (ribonucleic ...
