A nucleotide is the basic of polynucleotide chain of DNA and each nucleotide is composed of three components - i) a nitrogenous base, ii) a pentose sugar and iii) a phosphate group. Nitrogen base is attached to the pentose sugar by an N-glycosidic linkage forming a nucleoside. A phosphodi...

DNA has a structure called a double helix. Nucleotides are attached together to form two long strands that spiral to create this structure. If you think of the double-helix as a ladder, the phosphate and sugar molecules would be the sides, while the base pairs would be the rungs. The ba...

半乳糖唾液酸沉积症的英文名字是Galactosialidosis。基因解码表明:佳学基因通过基因解码发现:半乳糖唾液酸沉积症是由基因突变引起的遗传性疾病。该疾病是由于GALNS基因的突变导致酶缺乏,进而影响到半乳糖唾液酸酶的正常功能。这种突变可以是由父母传递给子女的遗传突变,也可以是新的突变。
Watson and Crick discovered that DNA had two sides or strands, and that these strands were twisted together like a twisted ladder — the double helix. The sides of the ladder comprise the sugar-phosphate portions of adjacent nucleotides bonded together. The phosphate of one nucleotide is covalentl...
CeCl3 binds to the phosphate backbone of DNA, which thus neutralizes the electrostatic repulsion, allowing the Z-DNA form to be energetically favored (Bhanjadeo et al., 2017). We first confirmed that CeCl3 induced conversion of gDNA to Z-form (Bhanjadeo et al., 2017) in a dose-...
DNA: Structure, Function and DiscoveryNucleic acids are the organic materials present in all organisms in the form of DNA or RNA. These nucleic acids are formed by the combination of nitrogenous bases, sugar molecules and phosphate groups that are linked by different bonds in a series of ...
3g). Previous work has established that cyclic stretching can increase levels of reactive oxygen species (ROS) in a range of cell types through activation of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase systems and mitochondria41. ROS have an important role in signal transduction, for...
This modification is installed in the endoplasmic reticulum (ER) by the DPY19 enzymes in metazoans: integral membrane proteins that use dolichol-mannose-phosphate as a glycosyl donor to form a C-glycosidic bond between D-mannose and tryptophan residues within the WxxW/C consensus motif2,3,4,5....
