If it is a long run, 16 gauge is preferred. If the run is very short, you probably can use 18 gauge with no apparent difference in sound. But the cost difference is fairly small, so 16 gauge is preferred. There is no shielding on speaker wire, so the covering is of little import.
The backbone of the DNA strand is made from alternating phosphate and sugar residues. The sugar in DNA is 2-deoxyribose, which is a pentose (five-carbon) sugar. The sugars are joined together by phosphate groups that form phosphodiester bonds between the third and fifth carbon atoms of adjacent sugar rings.
DNA is made up of molecules called nucleotides. Each nucleotide contains aphosphate group, a sugar group and a nitrogen base. The four typesof nitrogen bases are adenine â¦
