DNA doesn't act as a base because of the phosphate(H3PO4) groups in its backbone. These groups have acidic character because they are capable of...Become a member and unlock all Study Answers Start today. Try it
How are DNA and RNA different? A) DNA contains the sugar dextrose, while RNA contains the sugar ribose. B) DNA contains phosphate, while RNA does not. C) In living cells, RNA is usually a double-stranded molecule, while DNA can often be single-stranded. D ...
Thus, a DNA molecule is like a ladder that twists like a corkscrew, with the sugar and phosphate acting as the side rails and the base pairs acting as the rungs. Where Do We Find DNA? DNA is an extremely long molecule, so long that if all the DNA in a human was uncoiled and plac...
three times for 10 min in PSBT (phosphate buffer þ 0.3% Within testes, sperm develop within cysts composed of Triton X-100) and DNA was stained with either 40,6- two somatic cells (cyst cells) surrounding a number of diamidino-2-phenylindole (DAPI) (1.0 mg mlÀ1) for 5 min ...
IGF-1 has been modified to contain a heparin binding domain, a feature that enhanced its localization to cartilage after intraarticular injection in rats [200]. Ideally, a therapy would be off-the-shelf, with a long shelf life. This has led to the interest in gene activated matrices, ...
Other enzyme assays (succinate-cytochrome c reductase, succinate oxidase, NADH oxidase, glycerol-1-phosphate cytochrome c reductase) have been described [38]. The effect of quinone concentration on the initial velocity of the succinate-DB reductase activity was measured by varying the concentrations ...
The majority of plasma cells within the infiltrates contain IgM (i), while the number of IgG (g) and IgA (h) positive plasma cells is low; j: IgM containing plasma cells are also diffusely dispersed in the lesion parenchyma; k: at the lesion edge IgM is seen associated with myelinated...
1. Fish oils contain high, but variable, levels of omega-3 long chain polyunsaturated fatty acids (n-3 LC-PUFA), including eicosapentaenoic acid (EPA; 20:5n-3) and docosahexaenoic acid (DHA; 22:6n-...
DNA Structure The DNA (deoxyribonucleic acid) structure is described as double helix. The structure is composed of molecules called nucleotides. Each nucleotide is made up of a sugar backbone, phosphate group, and nitrogen bases. The sugar present in DNA is deoxyribose while the nitrogen bases ...
Fill in the blanks: Structurally, the monomers of RNA contain the sugar and the nitrogenous bases and.What are subunits of DNA and RNA?RNA nucleotide: phosphate + sugar + N-base Name the sugar used in RNA. List the four N-bases that are used in RNA.What are the components of DNA ...
