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.
A DNA molecule is made up of numerous genes and are found on chromosomes. DNA contains monomers called nucleotides, which is made up of a phosphate group, a deoxyribose sugar, â¦ and a nitrogenous base. These nucleotides connect together to form the double-stranded structure, called the double helix.
